Mercedes C220 CDI
Fault code diagnosis 2054 & 22A5
hi,
I have a 2009 C220CDI W204 which has constantly had the engine management light on for a few motnhs now.
anyway the garage gave me a read out of the following fault codes
2054-007
22A5-008
and said basically it would cost £800 to repair
I cannot now remember exactly what was said as I was in shock at the cost of repair but can anyone elaborate exactly what these fault codes mean and what work needs to be done here.
I recall the mechanic stating something about the gearbox manifold being removed which the part itself costs around £500 and that I needed to supply a log book, utility bill and proof of id to get the part ordered from MB direct.
so speaking back with the mechanic he has said I need a new temperature sensor for the exhaust which inc labour is around £150.00
The main job however is the gearbox going into limp mode although this has only happened on a few occasions the mechanic has said I will need either a a new conductor plate or a electro hydraulic unit which is around £800

C220 CDI W204.008 2007
C220 CDI W204.008 646 engine 2007 135,000km, engine warning light On.
Checked with my MB2 iCarsoft diagnostic, first DTC 2054-00 is:
"The analogue/digital converter to the CDI control unit N3/9 is faulty",
Have just driven 500 km for 35 l diesel, so 7 litres/100 km is nothing to worry about. User guide says to start worrying as I may damage the engine, but at least the consumption is OK. Question:
Does this error mean the engine is running on default values for injection volumes and other parameters? Anyone driven with the engine warning light on?
Taking the cover off from the ECU I noticed mechanics had already looked at the ECU as a plastic pin in the middle had been sheared off, which holds the cover to the ECU in place. Have they just wriggled the three contacts to the ECU to fix that same error?
Second error of 2054-007 is "Fuel temp sensor, open circuit or short" is easily tested via a multimeter before replacement, so that is no worry. Nothing to do with exhaust temp!
Buy a A0009050800 fuel temp. sensor, if that is the right model, from Aliexpress for US$20, take the corrugated air hose off, notice some brass colour below the fuel pump at the front, take plug of, check for 3 kilo Ohm resistance at the two pins, if open circuit or short use your 19mm spanner to replace it, that is what the web tells me.
Rather than taking the air hose off, etc. I thought I may as well buy the part and have it ready regardless of what the checking with the multi meter told me as I hope I can trust my iCarsoft MB2 diagnostic with the 2054-007 fault code for the B50 part with "Open or short" message.
My engine warning light is on, so I hope it will disappear after as those two errors may be related.
A STAR diagnosis would cost me AUS$250 and then fixing the issue is a AUS$150/hr affair. Fora tell me voltages must be right as low voltages lead to all sorts of ECU problems, but in my case the voltage at rest is 12.5V and charging is at 14.5V.
How did you get those error(s) fixed?
