Hi
i have a mercedes C220 CDI CLASSIC SE 2003 176000 miles
Please can you help identify my problem which has occured intermittently for the last year almost monthly
When driving along at cruising speed 60mph+ the car can have sudden loss of power,
the turbo I think ceases to opperate or it could be gear box as i speed declines and no throttle response or gearbox engadged so slowly i pull over hard shoulder and it then picks up again or i just stop turn off the ignition and again its fine, it make s me ginger and nervous as there is no faults on the dash for a mulfunction im confused.
will there still be diagnostic check for fault codes even if no mulfunction was on the dash ever?
if its a non computer issue will i start what should i start from the list below to diagnose it?
The problem is rectified by stopping the car, switching off the engine and restarting.
What needs to be done to stop this happening?
i think it might be something to do with the list below but where do i start due to the costs involved?
i looked at other blogs and got a list but where do i look first in order to remedy it some say auto box cleaning or fuel filter cleaning and other say::Oops:
Check the intake hoses from the turbo to the intercooler & the intercooler to the intake manifold - these are prone to splitting & only open up when under boost pressure from the turbo, so check carefully!
Also check the intercooler itself for signs of leakage.
Check the intake manifold - there are inlet ports that can leak, these can be difficult to see as they are located on the underside of the manifold close to the engine block. Large oil leaks from under the manifold are a sign that this is leaking.
The catalytic converters are prone to blocking & can sound like an air leak at times due to the pressure build up in the system from the turbo - inspect around the cat joints for signs of soot being forced out, another tell tale sign of this problem.
EGR can cause problems also if blocked so a check of the EGR system is advisable.
Sensor readings should be checked on a diagnostic tool such as Mercedes STAR diagnosis - the MAF (air mass) sensor can be a particular problem.
All of the above can cause the engine to go into limp mode which shuts the turbo down - the turbo itself can also cause problems but all of the above should be eliminated first.
Thank you for your help
