Hey, I have just bought my 3rd B5, a 1999 A4 1.8TQS Avant with 79k on the clock, having previously owned a '99 1.9TDi 110, 00' 2.8 Quattro auto, and a '02 4.2 S8 amongst other things over the past couple of years.
The car is in really good nick but I have a few faults to work through;
- The worst fault is a clonk from the diff/rear of the car when letting off the power, it can also be heard when in reverse, when you bring the clutch up and load / unload the drive train. This leads me to beleive its the diff carrier bushes, but I am yet to get under it and have a good poke about.
Does this sound about right? From what I can see there are two bushes in the rear beam / support, and a front mount. what bushes do people recomend? I dont want anything to hard as I dont want to make it drone / vibrate but I want to use this oportunity to upgrade if I'm going to replace. There is a lot of choice with the rear bushes at sensible prices, but the front bush seems to be rather pricey - so I'm hoping its on the rears I need.
- Temp gauge stopped working - popping to audi tonight to pick up a new coolant temp sensor.
- Doesnt always come on boost, Im going to check the vac hoses and waste gate is free to move. From what I have read I guess it could be N75, diverter valve, MAF, TIP, or a boost leak. I plan to replace most of these items anyway to ensure its all up to spec. I want to keep it all looking stock where possible.
Does anyone know if the N75J works OK with a 99' AJL? I have read that not all engines / ECU's accept the different valve? Or is it still pot luck.
- Headlamp washers dont pop up. No idea why not.
I have just ordered 5 litres of shell helix 5w/40 and will pick up a new filter from audi and get that done ASAP.
Thats all for now, im interested to hear your opinions.
