I decided to replace my camshaft belt/tensioner/idler etc ... also having the belt off I was going to replace the water pump at the same time, so too the auxiliary drive belt. I'd bought the Haynes manual to help me do the job!
My car is a 2006 Audi A4 Avant 1.9 TDI and the Haynes manual actually covers this model. What I would say is if you are anticipating doing this job yourself just be aware the Haynes manual is helpful but not completely accurate on a few descriptions of the job. (an instance is the removal of the front bumper assembly ... ""Remove the spot lamp trims and release the vertical bolts above the lamp units, totally inaccurate""" ... and some torque settings, ""some are printed wrong and don't convert"" ... anyhow it's a guide, just be aware though).
The water pump I used was a non genuine part, wanted a metal impellor type but the cambelt kit was genuine Audi ... the auxiliary belt was non genuine and after I took the belt off and inspected it, the old belt looked better than the "NEW" replacement I was going to fit. I actually just refitted the original auxiliary belt and kept the new one as a spare. The auxiliary belt can be replaced without having to take off anything, bit tight but can be done.
One thing worth mentioning for those that may be contemplating doing this job themselves! ... I ordered the part from AVS carparts. I waited for quite a while thinking the parts would arrive, after a while I contacted them wondering where the part were? It turned out they never had the water pump and had decided therefore not to send out anything! ... anyhow all was corrected easily enough with a phone call and the part arrived the next day, less water pump which I sourced from Europarts. I would certainly use AVS carpart in the future again.
Worth mentioning is that on the AVS carparts webpage that listed the correct part for my vehicle it recommends using the Camshaft locking tools "Sealey VSE 2358" this I ordered also. My A4 1.9 tdi has the engine code BRB ... and having double checked on the Sealey website that this tool is the correct tool for the above engine code, set about doing the job. I'm aware that there are two different types of crankshaft gear, ROUND and OVAL. In the VSE 2358 kit comes two crankshaft gear locking tools to cater for this ... a word of warning "NEITHER FIT" ... I actually spoke to a nice chap at Sealey tools and explained the difficulties I was having, but that said I ended up doing it without the use of the locking tools ... money down the drain!
After finishing the job I had to bleed the system, it states in the Haynes manual to "slide" the hose of the matrix pipe so the small hole just passes the tube and releases the air, all accurate I'd guess but in reality a sod'in nightmare, I ended up releasing the clip which without the correct type of pliers was a task and a half I got a long thick split pin and bent it so that it would go up the side of the hose and just about release the air from the system, heater bled and all was fine.
The idler was showing signs of wear (bearing dry and noisy) and I wouldn't have liked it to have run for much more than a couple of thousand more miles. The belt was not showing much in the was of wear but did feel a bit less supple than a new belt, the water pump "plastic impeller" was showing slight wear but not leaking, the tensioner likewise shown slight sign of wear as would be expected for component that had covered 75500 miles.
