SEAT Leon 2002 TDi SE - Couple of Questions

[Danny14]

Hello everyone,

As you can see I'm new to this forum, have been browsing it for a couple of weeks since purchasing my leon and thought I'd register as I haven't quite found the exact answers to the questions I have.

First off - I believe the Seat Leon TDi 2002 SE has a dump valve on already? Can someone please point me in the right direction of one that makes a whoosh sound when you change gear (big kid I know, always wanted one). Are they hard to fit and what sort of price am I looking at?

Also, I dont really know too much about exhausts - I want to take that van sound away from my Leon, or at least make it quieter, what do I need to do - Replace the backbox, replace the whole exhaust, get a tip? What's the price difference between them.

Final one I promise, I wanted to purchase some alloys - mine are 17" standard ones - how much am I looking at for some decent looking alloys with tyres but for not too much cash.

Really appreciate any feedback I get, sorry for the long posts, I know they're annoying

Many Thanks,

Dan.

<sigh> This question gets asked a lot.

Diesels don't need to dump boost on upchange, they have no throttle plate so there is no excess pressure to get rid of. No diesel has a dump valve as standard.

There are a few options open to you to make your car go "fsssh" on the upchange. All are cosmetic - they just make a noise at sort-of-the-right-time.

Anybody who knows anything about cars will laugh at you.


One more thing: your car could be a TDI 110, conventional distribution pump turbodiesel or a TDI 130, which is a PD engine. There's quite a bit of difference between the two.

In your service book, and also under the carpet in the boot, there is a sticker which tells you the spec of the car as built. The information is coded, but this VAGparts page gives you an idea of what the various codes mean. Your engine code (AML in the VAGparts example) gives us all a good idea of where to start. I'd expect yours to be ASV, a TDI 110 engine like mine.


Also, I dont really know too much about exhausts - I want to take that van sound away from my Leon, or at least make it quieter, what do I need to do - Replace the backbox, replace the whole exhaust, get a tip? What's the price difference between them.

"Van sound"? Please be more specific. There isn't much difference between the sound of a diesel and a petrol car - it's most noticable at tickover, and not unpleasent. Several regulars here have aftermarket systems, some with no cat, which emphasise the turbo sound.

Thank you for your quick response and I appreciate your patience with the questions I am asking as I know next to nothing about this.

How much would the aftermarket products mentioned be and are they easy to fit?

My car is the 110 TDi version, it says Leon MNO/TBU SportL41.9 TDISG in the service book.

Yeah the sound at tick over, I know it's VERY hard to notice when moving, I should have said I wanted to add a sporty sound to my car.

Thanks.

Are you sure you have 17" wheels as standard on an SE by the way? Any pics?

 

[Nutkin]

rs6 wheels will be cheap and look nice

 

[ryan106]

Don't know if its any help but there are quick a few people I have noticed with TDI leons who have put on a straight through exhaust who get a noise on gear change the straight through pipe gives it hard to type the noise though

 

[Nutkin]

ahh the mufflerectomy.

cheap and easy

but it makes your car sound like a labradors stuck in the engine.

 

[Danny14]

This isn't my car but it's exactly like it.

Any idea how much the straight through exhaust is and can it be easily fitted?

Also, anyone know how much these aftermarket kits are that make your car go "tsscchh" when you change gear?

Cheers

I'm sorry, I know Forge are a sponsor of this forum, but the advertising copy on this web page is some of the worst technobabble hype I have ever seen.

"Unlike mechanically derived products this kit has been created to symbiotically utilise the vehicle manufacturers latest innovations in order to allow the installation of an atmospheric dump valve to the VAG diesel engine. Information harnessed direct from your engine management system is interpreted by the supplied Electronic Valve control Unit (VCU) in order to optimise the activation of the twin piston valve. For ease of installation we have also created vehicle specific fitting kits that utilise silicone boost hoses, which can withstand the greater temperatures and pressures associated with performance engines, along with an additional wiring harness, fixing brackets, vacuum line solenoid valve and fitting instructions."

I suppose it does sound better than "this valve makes your engine fart when you dip the clutch to change up".

"To symbiotically utilise"? Howls of derisive laughter, Bruce.

Well, technically it's not when you dip the clutch, it's when you lift off

yeah right, couldnt agree more

Cheers for your help, just been waying up the pros and cons really and to be perfectly honest, the benefit that you get given the price is minimal, I'd probably be best leaving my engine alone (for now, would like an induction kit at some point) and getting some rims.

Just out of interest, has anyone colour coded their exterior black trims? The ones that run round the door and just under the light? The thought had crossed my mind, just wondering if it's been done.

Thought I'd post in this one again - can anyone point me in the right direction to find instructions on how to do a mufflerectomy to my tdi leon? Thanks.

colour code is sooooo last year... done mine but its booked to have them all plastic welded and smoothed in for the euro styleeeeee


mufflerectomy is easy, all you need is 1x hacksaw and 1x hammer.


cut the muffler off


then hit the pipe with the hammer

That's all it is? Have you got any pics?

I read something about putting on a straight through pipe, is this necessary as well?

Cheers.
