Hi there ..weird issue with my brother's Audi A4 2009 convertible BPW engine. It runs fine but every now and again when switched off it won't start again like the immobilizer has kicked in and norlt firing. The glowplug light doesn't come on. When it decides to go the glow plug light comes on...
If you unplug your coolant sensor and try and start the car. This defaults the car to -2°c and kicks the glowplugs in as if freezing cold. The glowplug light will stay on for approx 5 secs and if the car starts OK then you can eliminate most things like fuel delivery issue including air and the...
My b7 2.0tdi BLB was showing number 3 cylinder out and had bad idling. It turned out to be the injector lash needed sorting. Runs smooth now ..the clearance between the injector and the rocker was too much..
Hi there ..my audi 2.0 tdi had issues after being stood overnight and struggled to start but once started would run all day and start fine after.. then leave 8 hours or so and it struggled to start again..changed fuel pump , relay , battery , starter motor , fuel lines (air and making run back...
Hi..please can anyone help? I have gone to take out the glow plugs, however 2 of them will not come out. The one is just spinning around and around and the other is half way out but has now stopped turning. I currently have the head off and wondering is there an easy way to remove them? thanks...
As far as I'm aware it's only the BLB engine code which is a 2.0 tdi 140 bhp , (2005)which I have. Dont hold me to that though..maybe someone else will enlighten us ?
Make sure you avoid the BLB engine code, due to the oil balance shaft failing ! ..they all have issues however that's the worst as the engines seize up. I have changed on mine si far (B7 BLB)also EGR valve twice in 4 years , EGR cooler leaked , starter motor , fuel pump (cheap as a PD) , water...
Hi..can anyone assist? My 2 0 tdi had a water pump go and therefore took to a garage and had a new water pump and timing belt fitted along with all the pulleys etc.. had the car back and runs lovely, however I am now losing a serious amount of water..filling up after every trip. I have checked...
My a4 b7 is the same took the plastic cover off and full of oil and cogs chewed.. oil was also seeping through the electrical connector plug ..DOH! .. are these meant to have oil in the motor housing ??
For anyone else that has this, I have changed lots of things to eliminate this issue and I believe it was the "T" piece that fits into the fuel filter. I bought a new one from a well known online auction site which came with new o rings and the car is currently starting great! Was about 8 quid...
Just an update on this ..if anyone needs to change the matrix radiator and take out it is really simple in the B7 !! Firstly open bonnet and in the centre of the bulkhead you will see 2 rubber hoses one above the other ..undo the clips and remove the bottom one tonrelase water pressure (when...
This could be your camshaft timing. Check your torsion value in vagcom. Minus shows its retarded ..easy to adjust and a Millimetre makes a huge difference. Take top timing cover off and the right hand camshaft is the intake (adjust this one) mark the washer under the big 18mm bolt in line with...
Quick update ..I decided that all that was left was cam sensor and cam timing. I changed cam sensor (pig of a job) and still the same. I then proceeded to adjust cam timing and hey presto!!!!
Apparently after a few years the timing belt can stretch a little and this can throw your cam timing...
Check your engine number and if it's a BLB then possibility and if diesel ? ..it should give your engine code on your log book. It was more the 2005 -2006 model
This could be the glow plug relay which is under the ECU.. get windscreen wipers off (use a puller after undoing 16mm nuts) then remove the plastic scuttle panel that fits under windscreen (carefully) then remove the torx screws from around the ECU box under driver side windscreen and remove...
I fitted cruise control on my A4 and had to remove the airbag etc ..mine went off after a short drive. Get someone to reset with VCDS and scan for faults. Also check all connectors are back in place on the parts you removed. Good luck
Hi all ..changed starter motor on my B7 2.0 tdi BLB on the weekend and just wanted to share the experience to help anyone else.
Jack car up and get on axle stands as high as is comfortable underneath. Take driver side wheel off and you will see a plastic type cover than fits over driveshafts...
Hi there .. strange issue with my car. If the weather is cold my glow plug light stays on a few seconds and goes off and car starts straight away , however if the weather is above say 10 c the glow plug light comes on and goes straight off again and then the car turns over fires a few times and...
