new 4200 owner with MSP issue

[mjheathcote]

My first mot in the car in oct..i asked tester about rollers and that the car had an lsd..ne said no problems with that and just switch traction control off to make easier to get rear out of rollers...

Be interested if there was something official to say mustnt use rollers....

The computer screen on the MOT tester PC flashes up limited slip diff fitted to the car (certainly when doing mine) and not to do rear axle brake test on the rollers.
Fortunately I know the garage owner very well and do the MOT test next to him for a catch up chat!
Switching off the traction control does not help at all!
However, I suspect many testers ignore the warnings for an easier life...until something brakes, and then the owners finds out later not knowing the damage was caused by the MOT test as most owners are either not aware, not present, in the waiting area and can't see, etc etc.

Great info thanks!!!

You are right to suspect the diode, but save yourself some heart ache by trying a different diagnostic machine if you can - when I had a wheel bearing fail the garage could not get their SD3 to connect and suspected a diode, but it turned out that the machine needed an update.

Check for wheel bearing play on the front wheels (not much point at the rear as the bearings are clamped up by the driveshaft nut).

Does the ABS still work? If so then this is another vote for the diode, it could mean the ABS module is happily doing its job but just cannot communicate with the outside world. The most likely location of the diode is near the fuse box or in the cable run next to the trans tunnel. If you are really unlucky it could also be behind the dash near the heater I believe.

As anyone who has considered changing or has actually changed one will tell you, try everything else first.

Thanks everyone!!
I'm planning to get the second opinion on a different machine. This one was updated right before I brought in my car and I actually had to wait for it to arrive from the update. The ABS seems to work fine and no light on the dash. The only light I get is the orange MSP with the line across it.
The button on the dash is lit up as well and won't do anything- even when I hold it down...
No codes either but since they could not access the MSP system they couldn't pull the codes....
Just to be clear I was not asking about the brake check on the rollers since we don't do it here in the States but only about the diode because after searching the web I only found it mentioned here....
Thanks again...

This is just the legendary SM thread drift, nothing to be concerned about!

Based on what you are seeing, it does sound like the jump start popped the diode, but a second opinion would be advisable.

Thanks,
I had just pulled out the center console to fix the sticky plastic and while I was at it I pulled out the carpet and washed it.
I guess I'm going to do that again o get to the harness on the tunnel...
Oh well...

Thread drift my fault ... Sorry...

Got Second Opinion

I picked up the car from the dealer yesterday along with a 7 page report :
There are two codes :
Yaw rate sensor P1360- - not recognized
Side acceleration sensor(ay sensor) C1355- not recognized
apparently these two sensors are part of the same module.
He said he would need to spend more time searching.
I asked him about the "elusive " burned out diode in the wiring harness.
but he said he couldn't remember if that could be the cause.
He just remembered having nightmares trying to find it as its (the diode)location is undetermined. He said he spent days looking for it sometimes
The yaw sensor is not that much used- $250.
What do you guys think? - the diode?

 

[conaero]

I would say its the vertical accelerometer. This would figure as the car cant work out its level/yaw rate so this info cannot be fed back to the skyhook ECU and the shocks cannot be adjusted.

3200 one was under the left hand headlight and had a classic error where the counterweight fell off the sensor, glue it back on and it worked again, not sure where the 4200 one is, think its underneath/in the boot somewhere.

 

[jacekzaku]

Thanks I'll look into it!! Maybe a parts exploded view will help. BTW my car is non skyhook- just the MSP off light is on all the time and the codes point towards the yaw sensor. I'm wondering if the "non recognized " codes point towards no power to the yaw sensor i.e burned out diode... I know it's tough to judge these things on the net these cars are not simple- too many electronic systems...to keep us out of trouble...;-)

 

[CatmanV2]

From what I recall the diode doesn't throw any codes, does it? I'd go with the module

C

 

[jacekzaku]

I think that's where I'll start- the module.
An idea of it's location? The MSP module I mean... I looked on the exploded view parts drawing and it shows somwhere in the middle of the car.. or is it the yaw sensor.
A bit confusing I must say...
The yaw sensor would be another part to look at per Conaeros post...

 

[jacekzaku]

Found it!!
It's on the transmission tunnel under center console immediately behind the shifter switch. It was a bit confusing on the schematic because it's called "accellerator sensor" in Eurospares
part number 188172

 

[BennyD]

Think about getting any new bit/s from a main dealer. I'm having a major issue with Eurospares at the minute which I wouldn't want any of you guys to have to experience yourselves.

There is likely to be an upcoming thread on this in the near future. In the meantime, be aware that any part received from them that is found to be defective on fitment, will not be taken back. You have been warned.

 

[jacekzaku]

Thank you
I'm a bit off still from ordering as I usually arm myself with a multi meter and check the wiring coming to it first. (to make sure the power and ground on it are at the very least decent) Not a big fan of throwing parts at the issue and hoping for the best haha. Plus there is still the issue of the diode and it is likely to be located in the same vicinity as the yaw sensor/module (not sure what that part is actually- maybe both?)
Although buying (an inexpensive) part sometimes beats the **** out of $210/hr rate of a dealer mechanic diagnosing it....

My problems with Eurospares are the following:-

1. They're expensive.
2. Their postage is really expensive.
3. Their customer service is non-existent.
4. They will happily take your money but not order the part until you chase them for it.
5. They often send the wrong part.
6. They don't respond to orders on line.
7. They don't respond to emails.
8. They tell you they have a part, but then order it from Italy. But only tell you that when you chase them (by phone).
9. They don't know what manners are.
10. They actually have told me they are cheaper than a main dealer. Which just about takes the biscuit! (4 Centre caps, Eurospares £68 delivered, Gray Paul, £24 delivered).

No. They won't be getting my business again in a hurry.

 

[mjheathcote]

I buy all my parts from JCT600 Leeds.

Customer service is brilliant, the same parts guys have been there a long time.
You know straight away if in stock, or in stock Italy, with a definite delivery date to them from Italy.
They give you a ring when the part arrives.
Free delivery..I can pick the part up from them.
They will endeavour to price match.

Unless an obsolete part, or you want (cheaper) secondhand, can't see why you would buy from anyone other than a main dealer.

 

[MAF260]

I actively dislike Eurospares and will go out of my way not to use them. They're expensive for parts compared to main dealers, their postage is a rip-off, but most of all I have found them to be rude, arrogant, ignorant and downright disorganised at best. They have never returned a call despite promises to the contrary and IME/IMO are just an utterly shite, shambolic business.

 

[StuartW]

The best thing about them is their online parts database which is very handy for exploded diagrams and part numbers but I have yet to order from them so can't comment on their service

 

[allandwf]

In the 90s they were excellent. Perhaps they have just grown too large these days, and maybe lost focus.
