Hi, What is involved with replacing the throttle potentiometer in a 4200? Is this simple DIY? Thanks!

Hi folks, Have a 2005 facelift coupe (4200). It's not had a lot of use of late, and had lazy throttle pedal the other day (low power). Had happened before a service some months ago, but at that time I'd done the battery off for a few hours, then a min or so on MAR, 10 mins idling no input, and...

Hi there, Two squeaks to diagnose please... First is in the car - think around headlining / upper trim on passenger side. Sounds like a clip or screw vibrating up and down. There is general noise if you push on the trim around the window passenger side, and the part is loose that runs behind...

Hi, During some recent work, one of the passenger side bulb lens (white rectangular part) seems to have had the slips broken on one side. Is this part available separately? This is UK RHD car, with the passenger sun visor having flap, that when you open it, two lights come on on either side of...

So the 4200 facelift has gone through annual inspection and passed ... just. It seems there is some play in the rear wheels - related to the arms - lower most likely. Not clear if the ball joint or bushing. Worse on driver side. I posted on a noise in rear driver side arm before, and we...

Hi all, How do you get the boot (trunk) lamp out (the one that lights the compartment)? Do you need to remove the carpet effect trim, or just prise out the housing from the metalwork? Is it a 36mm festoon C5W? Was thinking of replacing with an LED. Thanks for your help :)

Hi all, I was wondering if it is possible to remove the Gransport front sidelight/fog cluster via the opening in the front bumper ("2" on the attached)? I can't find the opening underneath near "1"; perhaps this is only on the 4200 / 4200 facelift bumper? Mind you, I have been trying...

Hi Looks like my alternator has packed up in my 05 facelift 4200. As I have some extra load from audio equipment etc., I was wondering if there is a recommended upgraded / uprated alternator available? I imagine that the 4200 part is the same part as on the Gransport? Is it difficult to...

Hi there, I am having a heat issue - too much it seems... Temperature gauge is rising from the usual rock steady 90 deg C to 100 deg C when the car is fully warmed. It drops back to 90-95 deg when moving, then rises again when stopped at lights / slow moving traffic. This only started a...

Hi, Am having a spot of bother with the 4200 MY05 (Gransport geometry with springs replaced about 4 years ago, when lowered to spec, then checked a year later once settled to be correct height / geometry). Has Skyhook. Around 38k miles. It is clicking (click more than creak) - multiple...

Hi there, As I'm ordering some other parts, I thought I would try to order the red trident centre caps (wheel cups) for the painted standard silver Gransport 19" wheels. The part I have been suggested is 82364606 - but this is listed for the Quattroporte. An example photo is at...

Hi there, I've two questions please. 1. The passenger side air bag deactivation switch is giving trouble (confirmed via diagnostic). Eurospares are listing two different switch modules. Is 383310168 correct do you think...

Hi, Am replacing the bumper on my blue facelift 4200 soon. I see that according to Eurospares the Gransport Xenon/washer bumper is the same price (although it does show a separate front spoiler part which is confusing - I assume this is included on the "complete bumper" part..?). Which should...

Hi, I have the factory fit rear parking sensors on my 4200 facelift. Recently, the car was detailed/power polished. Some time later, I noticed the parking sensor feature was not working (the car still beeps when in reverse). If I put the car in reverse on MAR, each sensor makes s pitting...

Hi, I've recently noticed the temp gauge is creeping up over 90 deg (say to 95 deg or thereabouts) after 4k revs / then coming to a stop in traffic. Coolant seems OK in header and loud fan (full speed) seems to be kicking in. Some heat haze from driver side front so it is getting hot. Am...

Hi, I was wondering what are the recommended geometry settings for a Gransport? I have a facelift 4200, and it is setup as a Gransport - new springs / lowered to Gransport settings and aligned by the dealer (but I don't have a printout). It has the 19" Gransport wheels and skyhook. Usage is...
