[Turbo #3]

Yes it pegged the gauge and bent the needle.

Some times things really are as simple as they seem.

[Turbo #3]

Picked the car up today and what happened was that the waste gate rod had worn and caused itself to partially sieze under certain conditions hence causing the car to over boost and eventually destroy the turbine(see pic) .So if i had taken notice of when the car started to over boost more than previously and checked the waste gate rod with some thing as technical as a spanner i would have noticed that it wasn't  free and  smooth and not hanging up i would have saved myself a few bob.

Not sure yet ,getting car back tomorrow so will post some pics up of damaged part.

[Turbo #3]

Blade broken off turbine side,surged by the sound of it ,but awaiting tear down report,will post more when i know. 

[Where does all the water go?]

I fitted a genuine Lotus spec cap,as i said it did sort the problem out.I'm sure you can probably get a non genuine part if you have part number ,maybe there is one on your cap?(assuming it has the correct spec part fitted)

 

Just had a look in parts manual it states part number .   A082K6042F

[Where does all the water go?]

Yep that's exactly what mine was doing a new header tank cap sorted it out.

[Where does all the water go?]

Have you checked the expansion over flow tank on the left hand side of the boot floor? that can over fill and vent over board which you wouldn't see.Mine was caused by a dodgey cap on the header tank.

[S4s for sale]

I do hope so ,it kind of helps with my turbo issue

[Turbo #3]

Blades broken off the turbo Travis,obviously lucky its the hot side.

When i get a pic ill post it up.

[Turbo #3]

Yep i think the culprit(s) ,are a chipped engine and a free flowing exhaust and an over speed,but to be fair this one did last 8 years.Currently working on a solution,one being de-chipping,i did notice it was over starting to over boost a fair bit,one of those ,'i must get around to looking at that ' things.My car is like a beautiful woman when she is good she is very very good  and conversely when she s bad she is expensively bad.Suck it up and move on. (i do hope my Mrs doesn't read this) 

 

Eta .To correct appalling spelling

[Turbo #3]

As per title ,popped my turbo yesterday after a 'spirited' over take ,lots of smoke and a whining sound followed by a sinking heart and a depleting wallet.These cars test the patience of a saint,when they are good they are very very good but when bad....garage is of course trying to determine cause of failure i am errring towards wastegate actuator but will wait for diagnosis.

ETA. I mean 5th Turbo not 3rd........my mind was obviously trying to be kind to me 

[1994 S4, ABS telltale blinking, but no codes via Freescan?]

Exactly what Sanj has said

[Boost solenoid]

Update,fitted second hand 'new' gauge works a treat,also heli coiled errant engine mounting bolt,what a diffence a tight engine makes! I really should hang my head in shame for not addressing earlier.

Eta.Spelling and various words missing.

Thanks Derek

[Instrument light filaments]

Hi All

     Can any one tell me what the correct filaments should be on my S4s on all the instruments ,tell-tails etc ? 

 

       Many thanks

[1987 turbo esprit starting problem]

When it does this next time ,open bonnet and carefully depress the shrader valve(rag etc avoiding red hot engine) on the fuel rail to see if you have fuel pressure,you should also hear the fuel pump priming each time you switch the ignition on.It does sound like a fuelling issue.

[Boost solenoid]

Ok have trouble shot the boost gauge by shorting to ground and the gauge only flicks half way ,so  as i suspected the gauge is broken,now for a search now for another one.Unless anyone has a spare ?

[Boost solenoid]

Found it,it is behind the r/h quarter light panel sits almost on the tank,vac pipe was in good condition ,electrical connections and wire really shabby (looks like heat damage),but gauge does flicked when pulling connector off ,so i,m erring towards a bad transducer.may take it off whilst repairing wiring and give it a technical clout ,if i bridge the two connection's will the gauge just go to full deflection does any one know??

[Boost solenoid]

Travis ,i cant seem to see it,do you get to it  removing the carpet by the r/h fuel tank?

[Boost solenoid]

Thanks Travis ,i'll have a gander when it stops raining ......tomorrow me thinks .

[Boost solenoid]

My boost gauge has gone all 'floppy' it sets at rest far over to the left of gauge, but when boosting i am only seeing .5 bar (but i know by the feel etc that it is fully boosting so no problem there) anyone have any ideas,maybe the gauge has just died?

 

 

Hmmm come to think of it when the car over boosts which does happen occasionally the needle flicks like a mad thing.....so i'm thinking busted gauge.

[Does anyone know this S4]

Looks very nice apart from the colour which you can always get resprayed.
