So I’m having an issue with my Audi A5 TFSI Sport (2010) (2L) (180BHP). 92k on the mileage.
A few weeks back I was driving it all day, parked it up, and then went to drive it again later on and the car wouldn’t start with ease, I then had to hold the fob down and clutch for an additional 3-5 seconds than normal before the car was able to start. The car had lost power, was cutting out in first gear and really struggled. Engine Management light was constantly on.
I had it diagnosed at a mechanics and this error code appeared:
P001600 - Crankshaft Position, Camshaft Position Correlation Bank 1, Sensor A
The mechanic didn’t seem too sure what the error could definitely be; the camshaft sensor, crankshaft sensor or maybe an issue with my timing chain. So I decided to take the car away and do some research as the quotes I was given for a job that wasn’t confirmed to be the issue seemed a bit of a waste if it wasn’t the direct fix.
So after some research I decided to take the camshaft sensor out, take the part code down and order a new OEM part to replace it. I replaced the camshaft…no fix, the car still struggled to turn on, EML was still showing and as the car had now been parked up for 2 weeks it felt even more sluggish naturally. I let it sit to see if anything else would change, nothing.
So back to the drawing board I decide to replace the crankshaft sensor which was in an odd position of its own. I took out the crankshaft sensor, ordered a Delphi Sensor SS11319 as it correlated with the part code, fitted it today, started the car and the same issue occurred, this time with a bit more of a knocking sound from the engine initially before it quietened down.
At this point I’m a bit stuck with what to do, the vehicle is quite old and has a high mileage, I could take it to Audi to do a diagnostic and health check but they’ve advised it’s £160 for the diagnostic then anything else that needs replacing ontop, and with the vehicle already struggling to drive I’m worried of taking it to Audi, being quoted a ridiculous price for the fix and then being stuck trying to either get the vehicle out of there or having to fork out a fortune.
I’m aware this can be quite a common issue for these vehicles with age, but I just wanted to see if anyone has any knowledge, fixes or where to go from here.
I haven’t cleared any of the error codes since replacing both the camshaft and crankshaft sensor as I don’t have the diagnostic tools available , and so could this be affecting the car still believing the issue is present?
I’m just trying to think of all plausible fixes at this point, I’ve attached a photo of the diagnostic code, I have some more images of me replacing both sensors if required. Any suggestions?
