Around 10 months ago my van started blowing out black smoke and running flat out whilst on a journey.

I managed to bring the van to a halt as was towed to our local citroen garage where i was informed the engine had run on its own oil due to oil overfill and that had blown the pistons.

The garage charged me £2300 to repair the engine.

The van has been fine for around 9 months but a few weeks ago the engine started knocking loudly,i had the van towed back to citroen as the repairs had a 12 month warranty.They informed me that the crank shaft had gone,that it was not covered under the warranty of the repairs they had done and that i would have to pay for a new engine.

I do not know much about diesel engines but have been informed by a mechanic that the crank is very closely linked with the pistons and that they should of also replaced the bearings,and also that they should have advised replacing the engine particually considering the cost of the repair.

Can anyone help.

Have i got a case against the garage?
