Should I be worried

[brf1976]

Driving home from work today and the engine completely cut out (it wound down with no response from accelerator to a stand still) :( I put the hazards on and turned ignition off and back on and engine started up again as if there was no issue.

Question is this an indicator of a potential problem and has anyone else with a MG ZS 180 or other MG ZS had this issue?

Any responses would be greatly appreciated

Thanks!!

I've had similar in other cars but not the ZS.

What was the issue there?

The only thing I can think is I recently did a DIY air intake over the pipercross cone; which was tight and could of restricted the air to the filter.

I have since taken this ducting off and will replace pipercross cone with a K&N appollo enclosed induction as soon as pay cheque comes (budget restrictions as I know ITG maxogen is well rated).

Interesting, I had something similar on mine several weeks back, loss of power but didn't cut out, cleared after 20 secs or so and not happened again since.

Yeah hope it is a one off with me to as it just happened out of the blue. It was just like traveling at 50 in national speed limit and then turning the ignition off cause I think the steering lock came on to.

Just glad I was not on the motorway in overtaking lane

it sounds exactly the same as what my 206 gti did, they never found what caused it. The only thing i can thing of you doing is to check the plugs and wires that go into the ecu and also maybe check the condition of the ignition wires, ignition module and fuses

[talkingcars]

A common cause of problems is wires around the ECU rubbing through, could be that.
Or it could be the earth strap from the gearbox to the slam panel.
It could even be a stray radio impulse that triggered the immboliser.
On my Lada it was the contacts in the ignition switch that had burnt out.
On my scirroco the screw that was used to earth the fuel pump was too small for the hole which caused it not to start, once started it would run all day.

Sounds daft, but you havnt got a load of keys on the key ring???

If the lock is a bit worn, the weight of the keys after going over a bump could turn it off, or I have had my knee hit the keys and done the same thing.

Or as talking cars says, check all the earth and battery connectors, had a Volvo that would cut out, lose everything, then come back on. That was the power lead to the starter motor that had broken.

Cheers Andy will look this weekend just as a precaution

Cheers Talking Cars really hope it was a stray radio signal.

Update after taking ducting off big improvement in performance so could not of helped

I do as it goes I will take some off cheers peter

I'd check the ECU wiring. Or if there are any aliens around :hmm:

Sure Ive heard of similar things due to surges in pylons above. Not sure if its true, not sure how it would affect modern cars let alone the ZS there not much in the way of electrics most mechanical, cable throttle etc...

That or the supernatural!!

Way back in about 1986 I was driving anti-clockwise on the M25 just north of junction 10 (A3/Wisley) at about 1am. In those days at that time of night traffic was very light and the car in front was proberbly 5 or 600 yards ahead.

I notice his lights seem to go off for a moment, as I passed the same point the whole car cut out, the lights went out, the radio stopped, the engine stopped, a split second later it all came back on.

A few days later I was traveling passed the same point durring the day light and noticed that there are overhead power lines - I can only assume the 2 are connected.

The scirroco used an early form of injection known as K-jetronic which is purely mechanical, there were no electronics in the car apart from the radio cassete, this was before the days of CD players in cars, it was only just available in the home.

More modern cars using CANBUS (the ZT/75 has this and the mk2 ZS has a vauge crude version in the MFU) use electrical pulses in the system to control the the electronics. A electro magnetic field from a pylon could cause an extra pulse that would confuse the system.

Sounds to me like an engine sensor failing. Probably the crankshaft position sensor. Clean it up or replace it. My ZS 180 has the exact same symptoms as your describing.

Well whatever it was it has not re-occurred and I travel the same rout ever day.

Also there are some pylons nearby.

How costly is this to do?
