What is the problem?
-
Ok update on front doors not opening from key fob well I bit the bullet and took the door cards off removed the door lock took the little grey cover off and cleaned the linkages then used bicycle wet lube oil on the linkages and clips hey presto everything works
-
Take the car back it should still be under parts warranty
-
Any ideas my front passenger door will not unlock using the remote all other doors are fine it opens from the inside but not the outside could it be the actuator or a fuse maybe 2008 A4 b8

C/V joints 35,000 miles or not I had an A6 Quattro had the same noise at 33,000 I ignored it . It had to be carried home get it checked at trusted garage

Hi does anybody know what relay 643 is used for and relay 404 in my panel below the ecu are relays 457 ( glow plug module ) relay 643 (1 of ) and 4 relays 404
-
More progress terminal 30 must have 12 volts ignition feed it does not but also found out there should be a relay j317 it supplies power to terminal 30 so could this be the fault anybody know the location of relay j317 ?
-
Ok further to my previous comments I have no feed to the glow plugs I hooked a circuit tester from the glow plug feed cable to earth no voltage in fact I have no voltage at terminal 30 in the relay housing this should be battery voltage 12 volts why have I not ? All fuses on the battery are intact . No fault codes are shown , Any thoughts please the car still starts but not without turning over for about 10 - 15 seconds

Seals on rear lights defective need replacing or use bathroom sealant remove lights and reseal job takes about 20 mins

It’s behind the alternator there are 2 types fitted a single hose and a triple hose fitting

Possible fix I have been using Tesco diesel it does not contain an additive it’s also bio fuel which forms crystals in the fuel filter thereby restricting fuel flow , so am going to change the fuel filter then use a diesel anti wax additive to prevent the crystals forming fingers crossed, ps I am a retired HGV mechanic and have come across this before on trucks but never on modern cars
-
Thanks as I am a retired diesel mechanic 🚌 public service vehicles I ain’t going to give up yet I have a brand new 457 glow plug module to fit plus I have a few avenues to investigate will keep updates coming for other members
-
At the moment I have removed the glow plug module to test voltage supply I have checked the glow plugs resistance for all plugs is 0.1 ohms I have checked continuity of Reed wires to the plugs no breakages resistance is zero this reading is taken from the tip of the supply cables back to the module mounting socket. Should I have the ignition on when I test voltage from battery I believe this voltage goes through the engine management module before it gets to glow plug module ?
-
Engine turns normal no drop in battery voltage just turns then eventually fires after that car is fine , in the summer the car starts ok so am check supply feed starting with fuses in the boot on top of the battery then investigate forward
-
If you have a fault code P2015 go to eBay and google P2015 repair bracket it solves the engine light
-
Don’t get an inlet you can get a bracket to fit the inlet flap the light is on because the throttle arm is travelling to far back also how old is the car

Hello I own an Audi A4 2008 2.0ltr tdi CAGA engine code in winter the car is difficult to start (Summer it’s fine ) I replaced the battery , glow plugs and relay still difficult to start I have yet to test the voltage to the plugs the fuses in the boot above the battery are fine any thoughts would be gratefully acceptable .Derek
