Fitting the EGR Cheater

[Anonymous]

Hi guys,

Firstly, thanks for the great info in this and other posts on the cheater. Have a couple of questions you might be able to help with. I knew the eml was on when I bought my vx220 and the guy I bought it from had the code read which said egr valve. I took a deep intake of breath and promptly got £200 knocked off the price, knowing it'd cost be about £15 to fix really!

I actually had a go at making one myself. Made the blanking plate - snapped the bolt off so had to drill out and re-tap that! Made the cheater up, plugged in and disconnected the battery overnight. Was v happy when the light went out the next morning and no stuttering. Last night I was giving it some beans in 5th though and the eml came back on. I'm assuming it's my cheater that's broken, is there a way of testing the circuit with a multi meter? Is it just a case of testing diodes and resistors for values or can I test something on each of the pins?

Does it do any harm leaving the eml on? I guess it's better to not have it on as it might flag up another fault. Will I need to disconnect the battery again or will it just go out after a certain amount of driving if I replace the cheater?

If I can test it, I'll do that - I bought two of all the components I could. Some they didn't have, so I might be able to repair it, if not I'll have to buy the real deal from the site!

Mine is wrapped in a plastic bag, maybe it could have got moisture in as it was raining quite a bit when it was left outside at work yesterday?

Many thanks,

Nick

Hi mate, I bought an egr cheaer earlier in the year, hopefully you guys will have the record of it. Turns out it's decided to fail on me and now the car is stuttering like a kangeroo after 10 pints of fosters lol!! Problem Is I chucked away the egr valve and I went down to my mate garage who is a motor engineer and he said its causing the ecu to mis-read something kinda like an electrical fault hence the random stuttering. When I say random I mean it was fine for 7 days, however the last 48 hours has been impossible to drive and I had to nurse the car home tonight for work not ideal at 3am , strangley the engine doesn't splutter when the the clutch is in or when idling, only under load?

Anyway, I don't know if I can run the car without the cheater i.e just remove it as the blanking plate is in place or if you want it posted back to you to replace or if I need to pay for a new one etc, so drop me a line if possible on [email protected] so I can sort out whatever needs to be done mate.

thanks again

cheers matt, vocky also sent a pm saying that sluttering under load could be the coil pack so I replaced this today and the problem hasn't improved (I had a spare coil pack from last years engine that blew in may 2009!!) Easy job to change.

So thats a coil pack I know is ok, new plugs and egr cheater removed (until new one arrives) and the problem is sometimes smallish however last night regardless of gears or rev range the car was virtually undrive-able -- didn't matter if its -5 or like yeastarday in glasgow +8 degrees.

Any thoughts fellas?

Just an update -- it was the coil pack back then that failed.

Very odd now that 6 months later the same thing is happening?

Any ideas if the egr cheater can cause this as the spark plugs and oil were changed in feb, the plugs were black!!! I changed the coil pack and bliss ever since up until last wednesday.

The car is now very hisitant 1k rpm - 2k rpm regadless of gear, throttle postition etc.

I checked the oil which is fine, the air intake was fine and I cleaned out the throttle body, removed the battery for a few mins (as eml on) and then re-fitted the cheater from sratch making sure all the connections were fine etc.

I can get a coild pack second hand for £35 unless someone thinks it could be a different fault?

cheers

 

[vocky]

the egr cheater talks directly to the ecu and has nothing to do with the coilpack

 

[stewedw]

No probs, I'll change the coilpack and report back tomorrow or Wednesday

What if anything would cause the coilpack to fail?

New coilpack fitted, problem solved -- confused as to why two packs go in 5 months though notsure.gif

 

[vocky]

it is weird, but with about 500 egr cheaters fitted there have been no reports of coilpacks failing every few months

Yeah totally, Im not suggesting that the egr was to blame. After all it was a new donor engine fitted 2 years ago that has done 55k miles so perhaps there has been a loose wire or something thereabouts.

Something I just realise that is EGR dependant was upon refitting it and making sure everything is connected I have 2 Brown wires formally from the engine clip that subsequently need connected to the EGR, however only 1 wore is left. (I have the original egr not the clip one) therefore I don't know if I have connected the correct brown wire from the car to the egr or not? The car suns smoothly regardless of which one I connect to. The eml is on again now stating a lamda sensor problem, however when the motor engineer removed this he states the sensor is NOT faulty and that there is no fault on the cat or obvious emmisions or other faults. The crankshaft sensor and lamda were changed a dozen times under warranty so might be this

if this is in the wrong place then please move ta

 

[vocky]

just measure the resistance of the two brown wires, whichever has the least resistance is the correct wire

Yesterdays job was supposedly a simple one, disconnect the EGR, unbolt it, fit the new blanking plate and then fit the cheater, piece of pi55........would have been had one of the bolts not sheared off when undoing :x
What a ball ache, snapped off flush with the casting, couldn't have been the one furthest from the block, had to be the one closest just to complicate things.
Well what should have been a 20 minute job took 2 hours in the end as the remnants (80%) of the bolt wouldn't centre punch in either direction so I had to drill the bloody thing out and then re-tap the 8mm thread.....grrr. Most of the time was spent tapping the thread out using a small adjustable spanner instead of a tap wrench as there isn't enough room (had to adapt and overcome or not drive the car showo.. ) 1/4 of a turn at a time, as it was Saturday afternoon all decent Engineers Merchants locally were shut and Halfords have got jack 5hit in the way of specialist tools, I was sure I had a home made extension (a piece of bar with drive flats ground on one end and a hole up the other end with two bolts to grip the tap) but it has either been borrowed and not returned or has simply been lost over the years (although I can't say that I've seen it or needed it for that matter in 10 years or so ) .

All good in the end though, new thread in, blanking plate fitted (re-used existing gasket) and cheater plugged in, it was more of a preventative measure than a "need" as the car's only done 20,000 miles from new so the infrequent use it gets is likely to cause EGR issues eventually so I thought why not change it before I need to. It drives fine and no EML so far, so if anyone needs a working EGR valve let me know and we can strike a deal.

Oh, and thanks Neil (Vocky) cheers.. .

Hi
can anyone tell me what exactly should i use to prepare a cheater for non z22se?
How many volts, watts etc each component.
What kind of relay?

 

[Pisoiul Cel Rau]

which is the negative side of the EGR cheater? has disadvantages? can break something in time?

 

[vocky]

there are over 500 egr cheaters fitted and no long term problems reported yet dunno..

good morning im new here.
i have a 2.2 vectra which is a bit hesitant on light throttle, could a egr be at fault and will the cheater cure it?
i have had new chain,valves and alot of head work done recently as my tensioner bolt decided to snap!
my revs are about resiting around 500 and when i gently touch the throttle the go below 500 but does not stall.
hopefully someone could help.

 

[vocky]

might be worth fitting a blanking plate to see if it improves

hi,

is it possible to modify/fit this cheater for Y20DTH engine (Astra G '2003 2.0 DTI)?
i'm almost lost my mind finding any info on this

any help? TIA

 

[Daz]

Theres a fix bt vauxhall for the elevtric type egr valves. sure you just snip the grey wire goin to it and tape it up

[GMX2011]

you mean, i could just snip that grey wire and that's it ???
what will "see" ECU in this case? a "working" EGR unit ???

edit:
tried it - unfortunetely, this method doesn't work - "check engine" lamp still plays it's "on/off game" with power loss while it's on

apparently i need some EGR cheater, but i don't know what i need to modify in that scheme :|
i also know that it's possible, because i saw it fitted on '2004 Zafira (the same Y20DTH engine, same PSG16 ECU and electric EGR).

so, any help is really appreciated!

 

[vocky]

the z22se egr cheater only works on the z22se engine

best bet would be to get a replacement valve for a diesel engine

 

[admiral]

have just bought a egr cheater and was wondering how hard it is to take the egr off.am getting code p0404-(0) exhaust gas recirculation circuit range/performance (open)valve not present and am guessing the egr is duff.

just unplug the egr and plug the cheater in simply disconnect ur battery for half a hour it will take eml light away
