Evening all
Seen mixed reports about this engine, anyone got a definitve view of the 2.5L turbo diesel unit?
Is it reliable. Is it as torquey as a 2.5 petrol?
Cheers

It must have more torque than a petrol, if not it is a complete fail. All TDi engines have more torque then their petrol sisters. As far as i know it isn't much cheaper on the juice in town though.

Assuming you mean the M51 donk?
If the car is cheap enough they're not a bad thing to smoke about in at all. However, they're not that economical (when diesel was cheaper than petrol they made a lot more sense) and the diesel pump is expensive to replace in old age. An E36 318i is probably a better prospect IMO unless you're getting a free supply of chip fat!

no free chip fat so I think I'll stay with the petrol types...

Good luck using chip fat on a TDS. Unless you want to buy a new pump!

What a nice car for £600. Bargain basement money. Shame about the wheels though - they look gash on an E39, never mind an E34.

looks nice- plus the interior is pretty good.

I've got an E36 325 TDS touring manual, it's a nice engine, sounds nice, smooth, torquey, figure in the book is 195lb/ft, but the injection pump can be troublesome and VERY expensive.
I get mid to high 30's mpg, worse on the motorway, uneconomical above 75 miles an hour.
I'd reccommend LPG'd petrol for cheap running costs.

Can anyone suggest how to test if the boot lights are staying on with the boot shut?

Just binned my e39 525tds. Injector pump fail. Not economic to repair.

I owned an E34 525tds a few years ago and managed to get 700 miles out of a tank - driving like a granny!
I picked the car up for about £800, but must have spent about £1500-£2000 getting it fixed over the year of ownership - the engine just seemed to fall to bits
Don't think I'd get another one as the performance/economy/reliability and of lack of knowledge on the web for the M51 isn't great.

Previously owned loads of old E30s, E34s, a few E36s, E32s, E39s and an E38.
Currently in a diesel Audi - miss me old E30's....
