Ok some of you know I have never got my ams to run on my car. I have noticed for a while my car has a noticeable flat spot at 2400 rpm.under light acceleration, I mainly notice it in 2nd gear, I wonder if this has to do with my ams not running. Does anyone else's do this at that revs? My car is running standard just now, no ams.

I too had a flat spot that was, to be honest, a little intermittant. I would say, more hesitant than flat spot. Anyway, this was pre AMS and it turned out to be a faulty Fuel pressure sensor. It was just like a flat spot but quite intermittant. I too noticed in second gear and sometimes third, thou gears have nothing to do with it mate. I put up with this random fault for about 6 months and never really got to the bottom of it until it finally broke down altogether. After driving to the dealer they diagnosed the fault. Apparantly the sensor voltage was too high and made the car feel like it missed a beat. Was the ECU briefly putting the car into limp mode, hense the hesitation.

I can tell you one thing, after the sensor was fitted, boy did i notice the difference. It drove like a new car.

I do know they are a commaon fault on the P2 and they are very easy to fit and not expensive. Worth considering mate. I know you've already changed your MAF so it's the next probable thing to cause symptoms that you are experiencing.

Nice one Lee, it is exactly as you describe. Will get it changed once the bank balance improves slightly

Get the part from land rover and save about £130.00

10 minutes to swop.

[LeeT5]

Part only costs £151, so you telling me it's £20 from land rover?

Interesting. I wonder how many other parts on our cars, particularly V70R/S60R comes from other manufacturers at massively deflated prices?
I think a list would be in order.

[volvokid]

Wow Thank very much for that. That's a boost.

Kid;Give greenbank 4X4 a phone .Might be easier to go in past as they got fed up answering the phone to garages that just wanted advice.
They are the kings of Land Rover in aberdeen not Town & County the main dealers.

[volvokid]

I thought you might suggest them I will go in past, won't be today though, I don't have a car at work

Well after Graeme kindly loaned me a new sensor I fitted it along with my AMS took the car out and it started it's usual rubbish. Going to fit the old box back on and see if the stuter has gone.

What is this ams lark?

[volvokid]

It's just a induction kit

[jdavis]

ahhh, seems strange to have problems after fitting just and induction kit. have you tried the old disconnect the battery then reconnect after 10 minutes in the hope that it resets the ecu? is it definately the same part number of those others have fitted?

[volvokid]

Yip it's the IPD one, they are all the same, I've tried battery resets, changed my MAF, and TCV now the fuel sensor. Still no joy. Volvo can't diagnose it they just tell me it's the after market part that's causing it.

This is my AMS and the kit that Martyn is talking about:



This is the car with the standard air box:

Mate, ive told you before and i'll tell you again....IT'S NOT YOUR AMS CAUSING THE PROBLEM.

Go to your dealer, give them my phone number and i will bloody well tell them myself!! I've had my AMS on my car now nearly 18 months and ALL my problems that manifested themselves after fitting the AMS have now been sorted.
I'll list them for you;
1. MAF
2. Fuel pressure sensor
3. TCV
4. Clutch (yes, clutch. Mine was slipping under high torque at around 3 - 4,000 rpm when giving it the beans and i too thought it was the TCV mucking about!)

Now all these problems have been replaced, fixed she now runs sweet!

The AMS has Bu g ger all to do with any problems your getting mate, it just causes problems to manifest themselves because of the higher air flow. Any problem on your car will always be disguised until you start modding and making things go faster.

I had a knackered MAF for 4 months but didn't know. Just put up with the intermittant problems and thought they would go away. You gotta trust me on this one fella, else your never fix your car!

Take it back to the dealer, tell them to look harder and stop fobbing you off. If you have a problem with your car its NOT the AMS. It will be something not right else where. There are other ppl on this site with AMS's and their car run sweet too!

If i'm wrong them you can have my car F.O.C. (you gotta collect it thou)

[volvokid]

I know it's not the AMS Lee as we have spoken about before it's just finding the faulty part in my engine that we can't find
