Exactly the same thing happened to me when I was travelling at 60 mph down the motorway. Mine happened at 140,000 miles, so I think I was very lucky.

Bought my first 1998 306 Dturbo S 3 weeks ago, thought it would be good practice to change the timing belt and filters. 3 hours later the engine locked up pulling out of a parking space. After bump starting the car, it now smokes and runs on 3 cylinders at low revs, suggesting it has probably hydrolocked a cylinder and bent a con rod. Does anyone know if this is also a symptom, or just a faulty injector and my bad luck?

Same thing happened to mine (1999 306 Dturbo with 87k miles), was accelerating up a hill about a mile from my house, and without warning a large bang. It was still running on 3 cylinders until I saw the hole and large amounts of oil pouring out. Got a second hand engine for £300 from a scrap yard, after researching this I now think I’ll sell the car on when I get it fixed.

Hello everyone, I'm so glad I came across this site, as with the rising fuel costs and my driving job, I was considering buying a 2nd hand 306 d turbo, now I am defintely not so sure. I had a similar experience in a Renault-11 doing 80mph on a duel carriageway, that was scary enough and I don't fancy repeating it, Could anyone please tell me if the non turbo engines are more reliable in the 1998 peugeot range. thanks

I have heard that unplugging the green connector behind the battery for the EGR valve can increase the life of a diesel 306, a decat would accompany this nicely as they work with each other, IIRC a diesel before 2001 will pass a UK MOT with a decat pipe attached.

My 306 d turbo blew conrods out, and broke the starter and radiator in the process. Was a dirty mess, but it doesn't put me off them. Am NOW on my fourth 306. They are a great car.

It's only the engine with DYH code apparently, and only with the April 1997 - April 1998 car, mine is registered in March so I'm hoping I missed the fault by a month LOL.

My car, a 1997 R reg TDLX is now on 54,000 miles from new and going strong.
Famous last words perhaps, even though I'm very fastidious about oil and filter changes, and maintenance in general. It has a stage 1 Allard tune with a LongLife stainless free flow exhaust with no cat plus a K&N filter in the standard airbox and gives me over 60 MPG on a run and high fifties locally. But thanks to a previous poster who recommends removal of the EGR plug, I might well give that a go myself.
The Mark 2 models of this XUD engine don't rev out as well as earlier models, perhaps in part due to a slightly longer top gear. The fuelling and boost could be upped to overcome this, but the economy would take a large dive. In this day and age, is it really worth the hassle?
