Finding an Audi 4.2 cam chain tensioner kit in Australia starts with one important distinction: the short chains in the cylinder heads are not the same purchase as a complete timing-drive overhaul. RunningRoo lists a left-and-right package with two short chains, two tensioners and two gaskets. This guide explains how to discuss that specific package with your workshop, rather than treating every Audi or Volkswagen 4.2 V8 as one interchangeable engine.
You can inspect Audi 4.2 cam chain tensioner kit Australia at RunningRoo and the matching RunningRoo eBay listing before requesting a fitment check. RunningRoo is Australian-operated and offers friendly support from Blackburn, Melbourne. Call 0425 890 125 with the VIN, engine code, existing OE references and the workshop's findings. Melbourne local pickup is by appointment; ask about fast dispatch once the correct stock has been confirmed.

Which Audi 4.2 buying decision does this guide cover?
The intended reader has a workshop recommendation concerning the cylinder-head cam chain tensioners on an earlier 4.2 V8 and wants to understand the left-and-right package. It is not a guide to selecting a later all-chain V8 kit, diagnosing every cold-start sound, or purchasing a timing belt and water pump. Those are different decisions even when a search result contains the same engine capacity.
The product title uses the reference 077109088, while its written contents identify more specific left and right references. That difference matters. An abbreviated number in a search headline is a starting point, not a complete interchange decision. Ask the workshop to supply the full reference, including its final letter, for each required position. If a current replacement number differs, request an explained cross-reference rather than assuming that any matching numerical prefix is sufficient.
What Audi's own technical literature establishes
Audi Self-Study Programme 217 describes the V8 five-valve engine, including examples identified as AQF and ARS. Its construction overview separates the toothed-belt drive from the cylinder-head camshaft adjustment system. The camshaft adjusters are hydraulically operated, and the publication discusses their oil supply and starting behaviour. These details explain why a belt service and a cam-chain tensioner repair can represent different work on the same engine. See Audi Self-Study Programme 217, archived original manufacturer training.
The training document explicitly directs repairers to current technical literature for maintenance and repair. It is not a retail fitment certificate for this package. Its discussion of particular engine versions cannot be extended automatically to every A6, A8, S-model, Touareg or Phaeton carrying a 4.2 badge. The workshop must establish the actual engine and use the applicable service information.
Read the written package before comparing prices
The current RunningRoo description lists two chains with reference 058 109 229 B, one left tensioner with reference 077 109 087 C, one right tensioner with reference 077 109 088 C, and two gaskets. These are seller-listed references for comparison. They do not establish that the parts are Audi genuine components, that every supersession is interchangeable, or that the package contains every consumable required for the repair.
| Seller-listed component | Quantity | Question before ordering |
|---|---|---|
| Chain, reference 058 109 229 B | Two | Does the workshop confirm this chain requirement for both heads? |
| Left tensioner, reference 077 109 087 C | One | Does the full required OE reference match or have a verified replacement relationship? |
| Right tensioner, reference 077 109 088 C | One | Has the right-bank requirement been checked independently? |
| Gaskets | Two | Which sealing locations are covered, and what additional seals are required? |
| Timing belt, water pump and belt rollers | Not listed in this package | Are these separate items in the workshop's repair plan? |
A product photograph is useful for recognising the general shape of the assemblies, but it should not replace that written comparison. Pictures may not show every chain, gasket or packaging detail clearly. Conversely, an attractive photograph of a complete engine does not add engine components to the box. Save the seller's current written confirmation with the order so that the receiving workshop can check the actual supply against an agreed list.
Left and right need a shared reference point
A conversation about the left side can become confusing when one person is standing in front of the car and another is describing the manufacturer's bank designation. Avoid settling the question with a casual photograph alone. Ask the repairer to identify the required bank using the applicable service information and record the OE number alongside that position. The resulting description is much stronger than simply saying the noise is on the driver's side.
This is particularly useful when an Australian vehicle has an imported replacement engine or a previous repair involving individual tensioners. The registration details may identify the original car accurately while failing to explain what is currently installed. Tell RunningRoo about known engine changes and provide any engine identification available to the workshop. A physical part comparison and a reliable catalogue check can then be assessed together.
Diagnosis should define the shopping list
A recorded sound, a fault-code screenshot or a description of intermittent rough running can help explain the complaint. None of those, by itself, tells the supplier that both tensioners require replacement. Ask the workshop what evidence supports its recommendation, whether it has assessed the relevant oil supply and control system, and whether the primary timing drive requires separate attention. These are questions for a professional diagnosis, not instructions to dismantle the engine at home.
There are several commercially different outcomes. The repairer may identify one assembly requiring replacement, recommend a matched pair within a documented repair scope, or discover that the proposed package is only part of a wider job. Let that assessment determine what to order. Buying a pair because both banks are included is convenient only when the pair is appropriate for the vehicle and the repair plan.
If the mechanic cannot yet define the scope, ask for a staged quotation. The first stage can cover identification and diagnosis; the next can list confirmed replacement parts and any contingent items. This approach helps an owner understand what is known now and what may only become clear during inspection. It also avoids presenting a retail kit price as the final cost of returning the car to service.
Keep belt work and cam-chain work separate on the quote
An owner may see the word chain and conclude that a previous timing-belt invoice is irrelevant, or see a belt replacement record and conclude that the cylinder-head assemblies were renewed too. Neither conclusion follows from the invoice heading alone. Read the actual line items. A useful history names the components replaced, their references where available, the date, the odometer reading and the workshop that performed the work.
For this particular purchase, request separate quote lines for the short-chain package, any belt-drive work, sealing items, fluids, diagnosis and labour. If the workshop recommends combining jobs, ask it to explain the reason and the proposed scope. The article does not prescribe a replacement interval or insist that every adjacent component must be changed. Those decisions belong to the vehicle's service requirements and its inspected condition.
You can share Audi 4.2 cam chain tensioner kit Australia at RunningRoo with the workshop and compare it with the matching RunningRoo eBay listing. Both are purchasing references for the same narrowly defined package. If the quote actually calls for a belt-and-water-pump combination, ask RunningRoo about the appropriate offer instead of ordering this package on the strength of a similar photograph. Friendly support is available on 0425 890 125.
A useful enquiry for a Melbourne Audi specialist
Prepare one message containing the VIN, engine code, build information, full left and right OE references, and the exact product link. Add the mechanic's written recommendation and say whether the engine is original. If only one side has been inspected, make that clear. If the old number is unreadable, say so rather than completing it from an online listing with a similar appearance.
For example, a useful enquiry might explain that a workshop has identified the engine, checked the relevant service information and requested a left-and-right cam-chain tensioner package, but still needs confirmation of the final OE suffix. That gives the supplier a specific unresolved question. An enquiry that says only “2004 Audi V8 rattles” leaves the engine identity, fault and package scope open at the same time.
Do not post a full VIN in a public social-media comment when a direct enquiry will do. Send it privately through the business contact route or the eBay message function. Keep the fitment response attached to the chosen order, particularly if someone else will collect the parts or arrange the workshop booking.
Compare an Australian supply option on complete terms
When comparing offers, check the written contents, confirmed application, available stock, delivery destination and applicable return conditions. A lower advertised price may cover one tensioner rather than two, or may omit the short chains and gaskets. A larger kit may include items your workshop has not requested. The worthwhile comparison is between equivalent confirmed packages, not between the shortest product titles.
RunningRoo offers Melbourne local pickup in Blackburn by appointment and fast dispatch for confirmed available stock. Ask when the specific package can be released and whether the workshop needs it delivered directly. Dispatch timing and carrier arrival are different events, so avoid scheduling an immovable repair solely around an estimated transit date. Interstate buyers should provide the postcode when discussing delivery arrangements.
Receiving the package and documenting the repair
Before installation, have the workshop compare the delivered assemblies and labels with the confirmed order. Keep the left and right references distinguishable, check the listed quantities and retain the packaging. If a part appears different from the expected assembly, stop the purchasing comparison there and ask for clarification before the item is fitted. A clearly labelled photograph is more useful than an unsupported conclusion that a visually different part must be wrong.
After the work, ask for an invoice that records what was actually installed and any related work completed. An invoice saying only “timing repaired” is difficult for a future owner or workshop to interpret. Separate records for the belt drive and the cam-chain assemblies preserve the scope of the repair and make future parts enquiries more precise.
Frequently asked questions
Is this a complete Audi 4.2 timing kit?
No. The linked offer is described as a left-and-right cam-chain tensioner package with two short chains and two gaskets. It does not list a timing belt, water pump or belt rollers. A workshop should decide whether those or other items belong in a separate repair scope.
Does 4.2 litres establish compatibility?
No. Capacity alone is not enough. Supply the VIN, engine code and full OE references, and disclose known engine changes. The source literature covers particular early engine architecture; it does not make every Audi or Volkswagen 4.2 V8 compatible with this retail package.
Can I order using only 077109088?
Treat that abbreviated title reference as a search lead. The written package lists separate left and right references with suffixes. Ask RunningRoo and your repairer to reconcile the exact number required for each position, including any verified replacement reference.
Will replacing both tensioners fix a start-up rattle?
That cannot be promised from a symptom description. Professional diagnosis must establish the cause and the repair scope. The workshop should explain why the proposed assemblies are required and identify any additional work before the owner relies on the purchase as a solution.
Are the gaskets enough for the entire job?
The offer lists two gaskets, which is not a statement that every seal or consumable needed for access and reassembly is supplied. Ask the mechanic to compare its required materials with the written package and quote any additional items separately.
Can I collect the kit in Melbourne?
Ask RunningRoo to confirm the correct stock and arrange Blackburn pickup by appointment. Call 0425 890 125, or use the contact route attached to Audi 4.2 cam chain tensioner kit Australia at RunningRoo. If eBay is your preferred checkout, use the matching RunningRoo eBay listing and keep the fitment discussion with that order.
