There's nothing dumb about your question, Queensmith, so nothing to apologise for. And to answer your question, no, I don't sell cars.

elviszzz: Hi MR Sienna,I av an audi A6 1999 quarttro and am actually thinking of having the alloy wheels changed from 16 to either 17/18. If I eventually change it will this make my car thirstier/high fuel consumption Pls advice me Sir,thanks and hope to hear from you.

elviszzz: Mr Sienna,pls help. I own a 1999 audi a6 v6 quattro. When driving my car moves smoothly but when in hold up it starts jerking n dat continues for some time wit d check engine light blinking. If I decide to park n rest d car for about 30 mins,everything is normal agaim n wld drive smoothly until I encounter another hold up. What could be d cause of dis? Wld appreciate ur response.

elviszzz: thanks Mr Sienna,the check engine light only displays when the car is jerking,when d jerking stops after the car must have cooled down d cel light doesn't come up again until another traffic.

It still indicates a fault, and MUST be looked into, and any rectification work carried out. And a car being driven with a misfire is bad news, it should NOT be driven, until the fault has been rectified.

The most important maintenance item is the timing belt. If it breaks in service, you're looking at heart-stopping bills, in parts and labour. Bent valves, and possibly piston crown damage, depending on how fast you were going when the belt broke.

When replacing the timing belt, everything the belt drives MUST be replaced. In the 2,8 V6 30V engine, this includes:

01) Timing belt.
02) Timing belt tensioner (hydraulic).
03) Timing belt idler / relay pulley.
04) Water pump.

It is imperative the items listed above are replaced at the same time. It is pointless replacing just the belt. If the water pump seizes, it will bust the teeth of the belt, resulting in catastrophic engine damage. The same goes for the tensioner roller, and idler.

Replacement interval is every 60,000 miles or 5 years, whichever occurs first. When I purchase a car, the timing belt and associated parts are the first things I replace, if the previous owner can't satisfy me they've been done. The rule of thumb is to assume they need doing, and get them sorted ASAP. No if's, no but's. A timing belt can last well over 120,000 miles, but you're on borrowed time at this mileage, so cut corners, and ignore at your own peril.

@Siena, I've been a secret admirer for years and your posts here helps me alot. i run a 98 A6 2.8 quattro, 237k mileage, with no major complains but now I need original parts e.g, Valve cover gasket sets, OE stabilizer linkages.
Also, I NEED A STEP BY STEP GUIDE ON HOW TO SERVICE MY TRANNY. I'm a DIY freak ...I don't pay mechanics, I've done my throttle/valve body engine vacuum hose maintenance and so many other ...but I think the tranny is fragile.
please send it to me via email; realmexy@gmail.com
thanks
