EGR Problems
06. Apr 2011 at 19:50

With Mrs Loo-knee's Discovery.......

Ever since she has had it in the morning it is so sluggish for the first 100 yards its un true, but she got used to it thinking that was how these Diesels were...
Mothers Day we went doing the rounds when the Disco was going so slow a woman pasted us pushing a a pushchair ... well almost Grin

The smoke coming out of the back was so much the following cars had their headlights on Shocked

also showing their displeasure with more than a peeping of horns Grin

Monday I removed the EGR Valve blanked it off, it now is like a different car, unbelievable....

Apr 2011 at 21:39 EGR has a major impact on diesels as when its stuck open it means the exhaust pressure is lower resulting ina turbo that wont spin up. Having said that, its pretty essential on modern diesels as it makes them warm up SO much faster.

Apr 2011 at 21:54 Hi Daz, Yes, gives it a bit more power, also make sure the intercooler is clean and turbo hoses are all ok, have a habit of de-laminating on the inside. Other than that theres not much else to help them go any better lol Cheers, Iain

Apr 2011 at 21:56 Struggling to see how a decat alone can give any more real power as the ECU is controlling the fuel in and the boost pressure is limited......I am sure it would help with other mods though.

Not in the early 300tdi`s: the pump output can be 'tweaked' and the waste-gate arm 'adjusted'......How-to`s on most of the Landy forums. Thumbs Up!

....is the 'Cat' on a tdi not just a particulate filter and as such; prone to eventual partial/total obstruction? Undecided

I am sure it can be tweaked but, removing a cat is not putting more fuel in and hence power will NOT increase Thumbs Up!

Similarly for a larger intercooler, that will in theory get denser air in but....with out fuel its a fools errand

Exactly, it describes getting air in and then specificaly mentions how to add the fuel to get the performance.

Ergo, decat and larger intercooler does jack on its own.

Simples!
