Wiring Loom - help please!

Hi all,

I have a 06 TD4 which I have had from new and ever since the warranty ran out, guess what.....problems!

It has been spluttering and almost misfiring for some time and has been in and out of a local garage and they finally discovered a broken wire (leading to the EGR valve). They fixed this and the car was like new.

Then out of the blue this weekend, the engine warning light came on and the car lost power. Took it into the garage this morning and just had a call, the wiring loom has gone. Garage said that its only a small part that they need but Landrover no longer supply this on its own and you have to buy the whole unit Total cost £266.

As you can probably guess, I have no idea whatsoever about cars/mechanics! Now I'm sure that they mentioned the wiring loom when they fixed the previous problem but they've just said it has nothing to do with that. Can anyone shed any light here? Can you only buy the whole unit and does £266 sound fair? I know it isnt a huge sum of money but I've spent whats mounting up to rather a lot in these little trips to the garage recently!

Would really appreciate any help/advice from you knowledgeable people! Thanks

Right away my concern is that a relatively new car needs such an important repair. (Thinking Sale and Supply of Goods - merchantable quality etc etc) but before you have a rant at the manufacturer or main dealer, has the garage you use had it on a diagnostic machine? This will tell you which component isn't getting the proper signal or bad connection/ intermittent fault and so on. Unless you have been drowning the electrics in water or otherwise abusing the car then my guess is the loom should last years (One of our Range Rovers is 38 years old!!!) It could be a sensor away - they can be delicate and give up at any time. Whay does the garage say the loom is gone - is it brittle, corroded, burnt out? Is the car high mileage?

Those are just my thoughts and someone else may well be along later to tell you that it's normal for the new Freelander to need a new loom so early in which case I refer to my opening statement............

I think I would be tempted to go and see an auto electrician, the wiring looms are made by siemens and they are wire and connectors, and I'm sure the parts involved aren't that expensive. I would imagine a decent auto electrician would be able to identify and fix a problem on a car that is 4 years old???

a) where are you?
b) have they told you which loom/ part of loom?

Thanks for your replies. Yes they had it on the diagnostics machine & they said it was badly corroded and that Landrover said it was a common fault?! I don't know exactly which component is the problem but which ever it is, they claim it can not be bought on its own anymore.

Not high mileage - about 34,000.

Let's just think. They are admitting a common fault. The car is four years old and low mileage.

Unless you live by the sea and go through salty floods regularly then I would be asking Land Rover replace it f.o.c. especially if they know about the problem.

I had a similar problem, went to see an auto electrician and he tightened the connectors up. No problem for the past 3 years.

Just spoke to the garage (a general garage not LR dealer) again this morning and they said a wire has broken off right inside the plug going to EGR valve?? He said its the plug that needs replacing but LR have modified the part and now you have to buy the pressure valve as well as the plug. Does this sound like a plausible explanation?

As I said in my first post, I had a similar problem before but one of the wires had broken outside of the plug (but was touching for the most part which explained the intermittent spluttering) & was easily fixed once it was identified and the car ran perfectly. The only thing that I don't understand though is the engine management light didn't come on last time and the car didn't loose power like this.

I think there was a communication problem yesterday with the receptionist telling me that the wiring loom had gone & that the whole thing needed replacing!!

at the risk of repeating myself.

where are you?

most connectors used in the automotive industry are made by either Amp/Tyco or Molex and are "standard" automotive connectors. Any decent Automotive electrician should be able to get the correct crimps and be able to remake the connection.
A pic of the offending connector would help

Hang on a minute here guys. There aren't any electrical connections to the EGR valve so what are the garage talking about ?

This may not apply, but my Disco300 Tdi egr had electrical connections .. not to the egr valve on the manifold, but to the egr valve controller. OK, I have no egr valve now, but the controller, and it's electrical connection, is there, dis-connected and with the vacuum piping blocked with golf tees, but nonetheless there is an electrical connection!!

Mind, mine's a 300 Tdi Disco, not a TD4Freelander ..

EGR plug c0191 ns & rw there must be some slack to remake a new connector which are usually held by two barbs easily removed from the connector with a pin or jeweler screwdriver then the pin can be replaced and crimped or existing pin can be solder

But even if the EGR valve itself isn't being controlled by the vacuum solenoid it shouldn't resulted in misfiring or the spluttering the OP refers to. The EGR would just stay shut.

I had a problem with my TD4, took it in and they put it on the diagonstics, couldn't find the fault, so no charge.
