Title: Cam sensor: Pattern Parts or VX Genuine
Post by: going crazy on 18 January 2010, 14:38:58
My car now needs a new cam sensor and I need help on deciding if I need to go with a genuine one or a pattern part replacement.

My predicament goes further as VX decided to replace the old cam sensor (part number: 90458252) with a new part (part number: 93171450) and I do not know if I have the old one or a new one fitted to my car.

VX, I am made to believe does not do the old part hence it is only available via pattern parts, the new part would need a new loop to be soldered onto existing wiring thus increasing the cost of parts.

The cost of latter version of spares including cam sensor and wiring loop works out to be around £120 from a VX dealer while the pattern parts (new with 1 year guarantee) cost fraction of the cost.

Here are the links for a pattern old part number which will probably be the cheapest solution

Any experiences here of replacing a pattern cam sensor and especially the old model number (90458252) & background of why VX replaced it with a new part will be received with gratitude.

Secondly, new part pattern number links are

Please help me make the right choice as I haven’t got a clue and use the car very less i.e. less than 5k miles a year and haven’t had a trouble free time till date since I bought it a year ago. I am unable to decide if I need to spend more money on this or buy a new one – love the drive when it goes smooth but otherwise the problems do cost a bob as I am not handy and cannot store tools owing to lack of space

Thanks, Dave.

Any other opinions before I discard parts claimed to be manufactured by Siemens?

Can you PM me a picture of the sensor you have on your car.

I need a pic of the top on the sensor where the plug does in a two side shots.

if you can do this i can tell you which is which and offer a few options

Cheers

Andy, Many thanks for your response.

I am sorry but being a novice, I will have to instructed how to get to a camsensor in order to take a picture. Can help here in reaching the camsensor as I would want to know which one I am using i.e. mrk1 or mrk2.

PS: I have partial service history and will look thru the documents to check if it was ever replaced. I do not think I will be lucky though. >:(

there should be a "how to" for replacing the sensor which should show it in place
