Hi Peter

I am with you on this one

There is a thread about this with some varying opinions

http://members4.boardhost.com/ukautotalk/msg/1515947019.html

The ADAS system is calibrated on the production line via the sensor in the screen and usually in the grill. If the screen is replaced or the front of the vehicle is damaged then it has to be re-calibrated

If you are changing suspension parts (dealer or known quality brand) or replacing a tyre, then a front wheel alignment to the manufacturers tolerances should always be done. In my opinion this is acceptable

There are some points of view that is the wheel alignment is say 1 deg out then this would affect the ADAS system, I would agree

With the extremity poor conditions of the UK roads many vehicles everyday are suffering suspension damage or putting the wheel alignment out, but how many drivers rush to get the ADAS checked after going down a pot hole? not until 6 months later do they notice a NS tyre scrubbed out due to an earlier pot hole incident, so are they potentially putting other road users at risk?

So long as the wheel alignment is carried out professionaly and accurately to the manufacturers spec, then I do not see any real justification for an ADAS check

Selling ADAS equipment to the Independents is real tough sell, so a little project fear will help, will also help main dealer push up the price of a front wheel alignment, having told the customer an ADAS check is required

This is only my opinion. We need some statistics to show that accidents were caused by not having ADAS carried out after suspension or steering repairs. After an accident it will be impossible to check as the front sensor will probably have been destroyed and wheel alignment put out

PS
With the likes of ECP and a few other factors selling braking, suspension or steering parts to the general public at trade prices, then fitting them themselves or via a mate from down the pub, is a tracking or ADAS check EVER going to be carried out? as these vehicles get older, who will bother because of the cost of an ADAS check
