I have had my 1989 w124 300TE auto for around 9 months. Ran pretty well at first then started to use more and more fuel. Took it to a reputable local garage with extensive tuning experience they advised that the entire Bosch Fuel injection unit was U/S and needed replacing as it was "impossible to adjust the mixture". I procured a replacement used unit from a specialist breaker. Once fitted the car ran normally for around 3 months when it became thirsty again around 10mpg and lots of smoke.
I took it back to the garage and was dismayed at their news that the "new" fuel injection unit had exactly the same fault as the first. The breaker is supplying another unit as I write. The unit I mean is the whole gubbins under the air cleaner.
My questions are these.
Is there anything which could be "killing" these units or have I just been unlucky?
Does anyone know of a specific weakness with these units?
Any help, advice, suggestion or opinion welcome.
Thanks in advance
