Engine System fault

Can anyone give me any pointers as to what it could be?

Just towing caravan home with Disco 3, then after overtaking a vehicle above message flashed up on dash and cars speed decreased to 30mph.

Pulled off called AA recovered to chester services waited for AA mechanic, he arrived explained what had happed. Turn car on no fault message on dash, took car for drive with AA mechanic, nothing!

AA mechanic then suggested hooking car and caravan up and setting of home and would follow ups home.

Nothing happened for nearly 16 miles then just overtaken a lorry fault message again. Pulled off motorway, pulled over AA mechanic saw message on dash, asked me to turn car off and on again, did and message went.

AA mechanic towed caravan on his vehicle and followed us home, Disco worked fine all the way.

Mechanic did say that before I signalled him that I had a problem caravan swerved a bit, but I told him that I had towed and worst movement than that.

But fault is only happening when towing!!

Anybody got any suggestions????? Besides get rid of the caravan and Disco!!

Cheers

Mark

Get yer tea leaves read, could be EGRs or turbo and loads inbetween. When I had this (no caravan though) it was the turbo.

Forgot to mention AA guy plugged in his diagnostics kit, no error codes or messages came up.
He did say that LR do not give them access to all areas with regards to diagnostic codes (Don't if that true!)

Hi DSL, just done a search on ESF and just reading up on your problems.

Looks like it will be a trip to dealer and wait for the bad news!

Not all D3 codes show up on all faultcode readers (ISTR), might be worth finding someone with a Faultmate to read the codes properly do you're for armed before you get to the stealer. Thumbs Up

Could be fuel starvation, blocked filter maybe, but that would store an error code. Could be turbo actuator seizing, also should store a code as far as I know. Best get the vehicle to a dealer or suitably equipped tea leaf reader to find out what's going on.

Took it into dealer yesterday who ran a diagnostic and found manifold pressure fault, so they carried out a software update and carried out smoke test (don't know what that is?) and found pipe from airbox to turbo had come loose so the refitted.
carried out mini valet all for £70 inc VAT.

Brilliant if it works, so we will just wait and see.
