A4 Tdi oil pump chain woes
Discussion
Hi folks, was wondering if anyone can help with a problem i've got, my girlfriend rang me and said the car would't start (audi a3 2.0tdi bkd engine), then she said theres a light on the dash sayin low oil pressure!!! i nearly s##t myself, knowing the problems with these engines!!
Was hoping someone could help with info, will this have destroyed the engine or turbo etc? the car did not start at all but would have been turned over quite a few times, i then went up to the car and brought oil thinkin the oil was low and as the car was facing uphill on a very steep hill maybe the oil would'nt lift on the angle so i ran it back down to level ground and topped the oil up to max and tried but again the oil pressure light came on and the car still refused to start.
Gonna get the car recovered tomorrow and pull the sump of and have a look, i have a good idea what to look for as i've seen these pulled apart before but haven't actually done the work myself, any pointers would be a great help, thanks!!!!!

When you say wont start, do you mean wont crank, or cranks over but wont fire??Was hoping someone could help with info, will this have destroyed the engine or turbo etc? the car did not start at all but would have been turned over quite a few times, i then went up to the car and brought oil thinkin the oil was low and as the car was facing uphill on a very steep hill maybe the oil would'nt lift on the angle so i ran it back down to level ground and topped the oil up to max and tried but again the oil pressure light came on and the car still refused to start.

If it wont crank, then check battery and starter, but also try the rotate the engine by hand incase its seized.
If the car wont start but is cranking, its just because the starter isnt fast enough to make oil pressure, that you get the oil pressure warning.
Not having oil pressure wont cause a car to not fire, so there is probably a completely separate issue causing the none start injector fault (if its a 170bhp model), or maybe fuel pump or crank sensor etc for example.
Thanks for the pointers, turns out it is the crank sensor, now the next problem!, i have removed the oil cooler and the oil filter housing to get access to the sensor but i can't see how to remove it, audi need the make of the sensor as there are two dif ones in this car so i can't order it and see how it comes out that way, i have searched the best i can but i can't even find any bolts to hold it in place, i'm hoping ta jasus the box does'nt need to come out, has anyone fitted this sensor before?? thanks!!
Yeah i've been searchin all evening but no luck, i have even taken the starter out as i read on a forum somewhere that some vw/audi sensors are fixed thru there but it ain't on mine, i can't get a look straight in but i really can't find any bolt, i've searched the opening with a t20 torx screwdriver, if you know what i mean, but can't find the head of anything, i'm a panelbeater by trade and have done loads of mechanical work over the yrs so am confident with what i'm doin but i'm stumped with this bloody thing!!
Its definatly behind the oil filter housing, I use a 5mm long ball allen on a 3/8 drive.
The bolt is further in the opening than you would think.
This isnt exactly the one, but will be very similar, see the connection at the top and the thread of the bolt ar the bottom

My gut reaction is that these guys are rip of merchants if you ask me. They are charging £449.50 for the kit and the large Crabk sprocket, which is probably where cost is, last year I paid less than £80 for the kit, bar large sprocket. The large sprocket was fine, teath did not seem too worn. http://cgi.ebay.co.uk/VW-AUDI-2-0-TDi-BLB-ENGINE-O...
The ebay site says "THE CRANK SPROCKET IS THE ONLY ITEM NON GENUINE IT IS REMANUFACTURED AND HARDENED TO REPLACE YOUR DAMAGED OE GEAR". This sounds about right as I researched the large sprocket and Audi don't supply them, but surely its not worth £360????.
My gut feel is you may as well buy the new gear, it is £719 from Audi, i still have their quote. Note to replace the gear and chain, will still need future replacement in 50-70K miles, (if you are lucky!!)
Hi Folks, this problem is a complete nightmare and Audi don't appear to give a toss, but luckily for me I found an Audi expert in Coventry who converted my 2.0 Tdi BLB engine to a gear driven oil pump, basically converting it to a BRE engine, if you live anywhere near Coventry or can get your can there, I highly recomend this guy, his name is Mike and his mobile number is 07970 478931, he fixed mine for under £1,000 inc parts, with a warranty and that was including a cam belt kit with water pump.
He also has an Ebay shop where he sells Audi A4 Tdi engines and also offers a fitting service if your engine is screwed, take a look at this link 2.0 TDI engine AUDI, BLB on eBay (end time 10-Dec-10 19:44:41 GMT) or contact him via his Ebay user name volksbreakers. Any work is undertaken and he speacialises in Vw/ Audi, in paricular the 2.0 Tdis, but will quote you for anything, give him a go.
By the way, I am not related in anyway, nor do I have any financial interest in this guy, I am just passing on someone who I found to be great, when Audi quoted me over 2K !!

Hello folks and greetings from Finland. Decided to register just to let you know that converting to a gear drive system as per BRE engine DOES NOT relieve you from oil pump troubles.
As many of you know, in the gear drive system the oil pump is driven by a balance shaft, but the drive is still via the same laughable 6mm hex axle which is not up to the task.
I've seen 2 of these hex failures in a short time (within a month) and the latest one is just about to get finished. In both cases replacing only the hex axle was needed.
Both cars were 2008 A6's with the 2.0tdi pd (engine code BRE). Just wanted to let you people know!

You shouldnt just replace the hex drive. You should also change the balancer shaft, and turbo if its been damaged by low oil pressure.
The hex shaft actually spins at the balancer shaft end and then doesnt drive the oil pump. It only takes the edges off the hex shaft but once this has happened, the hex drive in the balancer shaft is worn until its almost round and new hex shaft will only work for a while before it spins again.
There is a TPI about this.

Hello. I'm new to the forums. I read this thread and have a similar problem. I have a 2004 A3 2.0 diesel BKD engine.Believe it or not it has only done a genuine 22500 miles from new. Went out to start it this morning and it wouldn't start. The engine was cranking quite fast but wouldn't fire. Then the oil pressure warning flashed up. Switched the car off then turned the ignition on again - no warning lights, cranked the engine again - low oil pressure light went on. So, got some oil from the boot, put about half a litre in and the car fired. The car was pointing up hill at the time. Car sounds absolutely fine when its running.I took it for a decent run and it didn't miss a beat. It started, stopped, fired up fine. I check my oil weekly and there is always plenty in it so i'm stumped why adding some oil made a difference. Is it maybe a one off glitch or could it be something wrong with the car like the oil pump or some sort of sensor??? Any help would be much appreciated.

You got the oil pressure warning because at starter motor speed the car doesnt generate enough oil pressure to push the switch in, the car sort or ignors this for arround 10 secs or so, so you dont get it every time you start the car, but if you crank it for long enough it will put the oil pressure warning up.Dont know why it didnt start, but it had nothing to do with oil being added thats for sure.
Hi all,I ve got Audi A6 2.0 TDi engine code BLB. Like mentioned above my oil pressure light came on so I drop it to my indy mechanic. He has stripped it down and confirmed it's not the oil pump but he has asked me to order chain,gear,sprocket,tensioner. Went to local audi and they said they are not selling it anymore. It all comes as whole assembly unit comes to £1089 with VAT. Had a search throught net and found out in USA they sell part with part number 03G103537B and it comes from Germany but suddenly I cant find it in Europe at all.
Any idea if the part is what I am looking for and if anyone knows where to get it or I have to buy expensive £1089 part from audi?
Thank you

Hi guys.
I found this thread through my desperate search for parts Chain - 03G 115 230
Gear - 03G 103 333 E and Tensioner - 03G 115 124 D having fallen victim to the same problem, and totally gobsmacked by the upgrade costs!
I did manage to track down the cog and tensioner from Northern Ireland courtesy of oempartfinder.co.uk but alas it seemed the chain was impossible.
Anyway, today I managed to find and order the complete kit from this guy:
http://cgi.ebay.co.uk/Audi-A4-A6-Passat-2-0-TDI-oi...
A really nice guy who is despatching it on next day for me, and garage is then fitting for around £600, so save probably about 50% on the £1500 + it would have cost.
I wanted to post this to help others as I wouldn't want anyone else having that sick feeling I have had since I got the £1500 + quote! - Am chuffed I found that guy - hope you enjoy!!
