1.4 tsi sounds like a diesel wnen idling

dfort1uk2 · Jul 31, 2009

I have just purchased a 1.4 tsi mk2 leon. I noticed it was very noisy on idle.
Dealer initially diagnosed "cam follower problem" and I left them with the car.

After help from Seat UK they said it was just a noisy fuel pump [which is driven from the camshaft on these engines]. They said they replaced the pump.

The diesel noise is still there and everyone thinks I have a diesel car.

Does anyone know if all these engines are this noisy. Dealer says they have reported this to Seat UK. I cannot belief the VW group would allow such a noisy engine to go into production. Anyone heard of a bad batch of fuel pumps maybe?

My MK1 1.6 petrol was very quiet on idle.

My Cupra's quite ticky on idle, I read its due to the high pressure injectors. May be the same with the 1.4 engine.

mine is the same from cold worse when it had just been serviced had to check the oil level to make sure the stealers hadnt ripped me off!

when i was in for my service last week , i was talking to the tech guys about problems common problems with the Cupra and he said thats nothing , the 1.4's are giving nothing but trouble , bad injectors ect , so best to keep on to them mate.

Can you get a video clip up of it as far as im aware all the TSI engine ranges sound like diesels due to the technology used to inject the fuel

Thanks for all your replies.
If as you say this is a characteristic of the TSI engine technology then that will put my mind at rest.
I will monitor it over the next while and try and get a listen to a few other cars.

My 1.4 TSI is very quiet on idle. Must be something wrong if yours is noisy. Done 20,000 miles and no problems so far.

My cupra sounds like a diesel when i start her up (when i turn the key) and when im letting the clutch out to pull away with some revs it sounds like a diesel,

robdf2 · Aug 1, 2009

i wouldnt worry , my Cupra is the same and my old 1.8t cupra also sounded like a diesel lol , its in the design.

farrar · Aug 1, 2009

The 1.4 TSI engine should not be noisy on idle.

My old 1.8t Never sounded like a diesel. It always sounded whisper quiet when cold or hot. A little turbo whistle when you gave it some..

It did have a silly mouse squeek that I never got to the bottom of but hey the cars gone now :shrug:

i have an 08 plate 1.4 tsi with 10k miles. i had the exact same problem and put it into the dealer under warranty. they replaced some sort of fuel pump that sits right at the top of the engine.

^^^^^^I think that sounds like an injector rather than a pump, sounds like a common problem on these engines

direct injection sound in all TSI and TFSI engines

is normal

iendicott · Aug 4, 2009

Our car has a slight ticking sound but I put this down to the way the fuel is sprayed into the engine.

just a bad design with the engine unfortuately mine sounds the same at 12k on the clock had my car for 1 year sometimes when it starts it idles at 1.5k rev then automatically lowers back to 1k...I didn't notice much difference when the oil was changed thats what I thought it was at first but yea should have a TSi meet and hear the difference.

stick it next to a NA of another make or older VAG engine and you will see the differnece. The tsi and tfsi's are not nice sounding engines lol.
