Mobile car diagnostics in Barrhaven

The codes read and, more to the point, explained: what the car is actually reporting, and what it does and does not prove. We come to you in Barrhaven, weeknights from 5pm and all day Saturday and Sunday, so the car is fixed without a day off work.

Why people call

What people describe when they ring about this

You do not have to know what the part is called. These are the words people actually use, and any one of them is enough to book on.

  • A check engine light, steady or flashing
  • A car that cranks and will not start, or starts only sometimes
  • Temperature climbing, or heat that has stopped working
  • A noise you can hear and cannot place
  • A code somebody read at a parts counter, and a part they wanted to sell you off it

Barrhaven, specifically

What we see on this job in Barrhaven

Barrhaven gets the intermittent ones. A lot of driving here is short arterial runs with the engine never quite up to temperature, and faults that only show cold are exactly the faults that will not repeat for a shop that has had the car sitting in a bay all morning. Coming to the car, first thing, before it has been started, is not a convenience for that job. It is the only way to see it.

On the truck

What turns up on your driveway

  • A proper scan tool, not a code reader: live data, freeze frames and the manufacturer-specific codes a generic one never sees
  • A multimeter and a test light, because half of these end up being a connector or a ground
  • The VIN decoded first, so the engine and the trim are known before anything is guessed at
  • You get the codes themselves, written down, whatever you decide to do next and whoever you decide to do it with.

How long it takes. Usually an hour, and often less when the code turns out to say what it means.

What we will not do on a driveway. A fault that only appears at highway speed, on a bad road, an hour into a drive, is not going to appear on your driveway. When that is what we are chasing we will tell you what it will take, and not charge for an afternoon of not reproducing it.

Where the car can be

Parking in Barrhaven

Barrhaven is a mix. Longfields and Half Moon Bay are wide driveways and easy work; the older townhouse rows off Strandherd and Greenbank are shared lots where the spaces are tight and sometimes on a slope. If yours is one of those, tell us when you book and we will bring the extra ramps.

Areas we are in most weeks: Longfields, Half Moon Bay, Stonebridge, Chapman Mills, Old Barrhaven.

What it costs

Priced after somebody has looked at it

There is no price on this page on purpose. A diagnostic job depends on the vehicle, the parts it takes and what is found once a wheel is off, and a number written here would either be wrong or be something you have to argue about in a driveway.

You get the cost of the work and the travel together, before anything is booked, and nothing is charged until you have said yes. The travel band for every postal code we serve is on the service-area page.

“Had to grab new winter tires and invited David and Kaden from Peakline Mobile Auto to come by tonight to my home and they did an awesome job installing them. They were fast, efficient and great to chat with. Great price point and great service. Highly recommended!”

“Great seasonal tire changing service this evening from Peakline, on my own driveway. They were punctual, friendly, and look to be well equipped for many auto services. Price was very reasonable, we’ll definitely be booking again.”
