Please guys help me out. So my car is e220d. Running perfect till two weeks ago it sounded loud but drove normally. Then I noticed mpg was lower on motorway journey I do every day of 27 miles twice. Then it stopped going into manual mode. Went onto YouTube and found a way to reset gearbox and it does work it’s starts going into manual again. Right now it’s staying in manual till I give a little push, by push I men’s just a little not the beans. Then it stays it auto mode put changes gear sluggishly. Took it to MB specialist they said I need a new camshaft cover at a cost of around £1500-£1700. Something to do with the bolts sometimes break but Mercedes told me they provide 29 new bolts when you buy a new one from them for £650 odd. I can buy a reconditioned one with 2 year warranty for £200. They refuse to fit it in case it’s not correct but I’ve confirmed with seller it is the correct cover.
after the long intro my question is can I not be repaired? I take it the gaskets are leaking which cost about £5 but I could be wrong. Someone please tell me there’s a way to do this affordable I just can’t afford it right now going through a costly divorce and having zero funds to throw at the car which I would have done a year ago.
