300CE 24v with petrol (gas) smell
For what it's worth, I had fuel smell and starting problems, particularly in hot weather.
Traced smell to leak from EHA (bolted to fuel distributor). Assumed that plastic washers were at fault and changed them - no go - fuel still weeping from around EHA.
Luckily I had a spare EHA (same part number etc.) from faulty 300TE 4Matic (different distributor) so installed that. NO CHANGE - still weeping.
I then found that the new 300TE distributor - removed EHA and installed that. BINGO - no leak and perfect starting.
I then had an idling problem so removed ICV (Idle Control Valve). Cleaned it up and lubricated it with WD40, together with the ICV from the 300TE (same part number, again). Replaced original 300CE 24v ICV - WOULD NOT IDLE AT ALL!!!
Recovered cleaned up 300TE ICV and installed that. Now all is well:
It starts perfectly from cold.
It starts perfectly from hot
It idles like a dream.
I hope these experiences are of use to someone, although the 400E that started this may be different.
All the best.
