Exhaust cooler has broken whilst towing the caravan to Bridgewater.

Can anyone recommend any indies around the area?

Anybody know a rough repair cost?

Need it repairing as we have days out booked. I'm frightened to use it now. I'm assuming it can damage other things if I carry on using it due to the loss of pressure?

Item no 1 i think

Any help appreciated.

AFAIK the corrugated section of pipe is integral to the EGR cooler - you may need to replace the entire EGR cooler unit.

In the meantime, as an emergency fix, I'd get some exhaust repair 'putty' or similar from Halfords or a motor spares shop. There's bound to be one nearby.

A hairline crack would just make the cats bit smelly but if the pipe has sheared it's potentially a lot riskier (exhaust gas being very hot could damage other components).

Ye it does look like a complete unit unfortunately. An expensive one at that.

I'm thinking of maybe going down the EGR delete route now - blanked off and coded out.

I've been trying to think of some sort of temporary fix. I'm thinking now of getting a steel scourer/wire wool, twisting strands together, cover in exhaust putty, wrap it around the split area and clamping with a jubilee clip. Hopefully that will stop a lot of the leakage.

Luckily I only had a few miles left when I noticed something was off.

Assuming you were towing within the maximum towing weight guidelines/tolerances.

How long ago did you have the recalled EGR replacement because you could have had a faulty part fitted if has failed like that. Worth checking because it was done within the last two years all parts have a two year warranty from fit date if done by BMW so you would probably only have to cover the labour costs. Or If you have an extended original or AUC warranty you will just have to cover the excess amount if you have one, regardless of part fit date.

Im not sure recall work gets the 2 year parts warranty, i could be wrong but i 100% remember being told that with something and i thought it was absoult horse$H17

As others have said, its trash sadly, id be very careful running it, you really risk of fire...

I would personally take it up with BMW, like goat has said has it had a recall? Although its the EGV valves that normally get replaced the cooler might of been damaged or disturbed when the work was carried out.

I asked that question when I had the EGR cooler renewed under the recall.
I was told it carried the same 2 year guarantee.

Correct. 2 years warranty.

Get yourself and the car up to Avon Tuning. They'll code-out the EGR and fit a blanking plate for £200.

You'd need to check where they insert the blaming plate though - no use if it's after the split in the pipe.

Thanks for the help guys.

I've managed to bodge it with exhaust putty, holts exhaust bandage repair then a jubilee clip.

So far it looks to be holding well, will be keeping a close eye on it. Drove to and from Weston super mare. Doesn't seem to be leaking much.

Thanks for the recommendation Watsey, will give them a ring in the morning and ask.

The car is a 65 plate 320d with a B47 engine. I've owned it for two years, bought from a main dealer. Never had a recall done I've also checked if it's due one.

Car was towing well within limits. Caravan fully laden weight of 1235kg vs car capability of 1600kg.
