Egr valve problem,

[lozz]

Anyone got any ideas on how the Egr valve works on the 110s,
Are they supposed to be open slightly when the car is running at tick over?
im getting a slight hiss from the valve too, the metal part -not the solenoid,

theres no loss in power but ican hear this critter hiss from inside the car now and then,
this problem as only started since ihad it re-mapped,
also the top air pipe for the intercooler sucks inwards when you rev the car not much just a few Mms
like its not getting enough air, Air filter is clean ,

i blanked mine off, the difference now feels less substantial. i think the novelty is wearing off.

blank it off lozz the blanking plate is only likr £4

[lozz]

iwill be leaving my egr on,
it saves on fuel in the winter , and with mine being fully mapped ithink its best left on,

the blanking plate isnt the hardest thing in the world to remove. I thought they were good for the turbos, the performance isnt really that different though.

iunpluged my egr once, to test,
theres no differnce ican see

De-cat and remap is the onlyway to get the most out of a derv engine me thinks

sorry lozz i had a xud xsara with 138k on it and the egr was blanked from around 80k and that was running it orignal turbo, that guy is chatting crap.

the taxi's i used to maintain 3 of em were renualt dti's and they did 300k + with no egr.

Yup he might be chatting crap, he seems to like throwing turbos away , new ones are over a grand he must think people have got deep pockets,

but still iwill leave my egr on his theory on this helping it vent the turbo may be correct

[FarmerPug]

he is on about the xud, we have the hdi.

i spoke to my mechinic about the blanking plate before i got it and got the ok from him before getting it.

A turbo is a turbo isnt it
whats the difernce

[FarmerPug]

im assuming the hdi uses a different type of turbo.

It cycles open / shut many times a second, but generally only when you're not touching the throttle.

If you want to test what it's like blanked off, disconnect & plug the vacuum pipe at the solenoid valve - this disables it without triggering a fault, (unlike disconnecting the solenoid valve). So long as the egr isn't letting by this does the same as blanking it off.

I was tempted to blank mine off, but with remap, V6 zorst, and decat, I was particularly interested in gaining more power

Anyway, I thought it would, but wanted to play safe with it passing the mot with the way it is

[jamjar1383]

most egr's are so gunked up they dont work anyway.

What is the best stuff to clean them with ?

is there anything out there that ican just pour in the tank and itl work its way thru cleaning it?
idont fancy taking it off or paying £98 for a new one,

thanks inadvance.
