PUMA TDCI 110 & Warranty

ellebarto · Dec 13, 2011

Traded in a 10 month old Rangey for a 2010 Defender with a view to speccing it up for expedition type trips and some off roading. I contacted the previous owner and the car had suffered from the usual warranty recalls that had all been resolved.

One issue stuck out because it was never really explained with the dealer just claiming a fix. Basically after long continuous use at say 70 mph, so motorway journeys, the turbo cuts out and the engine management light comes on. Restart the car and the problem goes away. Now since getting it I've put on a bigger intercooler and a snorkel with sports air filter and even though I can demonstrate its the problem previously found and not addressed they wont touch it until I take the intercooler and silicone hoses off. Seriously dislike Landy dealers. If I'd strapped on a big turbo then fine but this is just silly. Anyone else have this kind of behaviour? Error codes are P1103-00 Mass air flow sensor in range but higher than expected and Turbo/supercharger overboost condition.

Any help or advice appreciated. My favorite comment from the dealer was that they couldn't tell me about previous error codes until I restored my engine back to OEM condition!!!

Who read the codes? were they deleted and then the vehicle driven to get them to re-appear? what were the live data readings?

It sounds most likely to be the EGR valve as it happens when driven for lengthy runs at continuos speeds

had terrible service from main dealer when i bought a nearly new disco would rather pay back street prices and take my chances rather than let them bleed me dry good luck with your landy mate

Its the most frustrating thing. I mean I know I've modded the engine, slightly but the problem is the same as the previous owner reported. I have various emails from her describing the fault in detail. They have actually given me a pdf of the codes they have this time. Initially they said it was impossible to get the codes from the previous ownership but then I asked them to confirm in writing that they couldn't get them and amazingly they have gone off to get them now. I wonder where I stand if the codes are the same but I've clearly changed the engine. A few people have suggested the EGR valve but I'm sure thats been done under warranty already.

It may also be the MAP sensor kicking the ECU into limp mode if it thinks the turbo is overboosting. First off I'd give the sensor a good clean then if that does not cure the problem fit a new sensor. If it keeps doing it then dial the turbo down a tad (literallly half a turn longer on the actuator rod) and see if that solves the problem.

OK, well this issue has progressed a bit and I wondered if anyone had any further input.

Basically, Ive had two big laning days in the car and the fault has not re-occurred. Keeping in mind it did happen like clockwork in the circumstances I originally described. So I looked at the changes I have made.

Firstly I had a side exiting exhaust put on but that was virtually the whole original exhaust re-engineered. There was just one very short piece of straight pipe added. Making a Side Exhaust for Defender 110 TDCI - Stu Beckett - YouTube

Secondly, I hadnt fitted my silicone turbo hose very well and it blew off on the motorway on the way home one day and I drove it for about 5 miles like that before I stopped and sorted it. There was a hell of a lot of greasy oil blown out around the pipe.

Do either of these changes sound like something that could have affected this fault?
